                           July 16, 1997


Before SMITH, BARKSDALE, and BENAVIDES, Circuit Judges.

JERRY E. SMITH, Circuit Judge:



      Roger Gresham challenges his convictions of possession of a

firearm   by     a    convicted   felon,     in   violation   of    18   U.S.C.

§   922(g)(1),       and   possession   of   an   unregistered     firearm,   in

violation of 26 U.S.C. § 5861(d).            Finding no error, we affirm.



                                        I.

      Gresham and Cheryl Taylor lived together for many years, but

their relationship ended in 1995.              Following their separation,

Gresham resolved to build a bomb and take revenge on Taylor.                  He
carelessly discussed his plans, however, leaving an incriminating

trail.    At trial, witnesses recounted the evolution of Gresham's

plot in damning detail.



                                      A.

     Gresham and Taylor were living together in Kensett, Arkansas,

prior to their separation.      As their relationship began to erode,

Gresham regularly complained to the Kensett police chief, Ralph

Jordan, that Taylor was stealing his property while Gresham, a

truck driver, was absent on his routes.               In one conversation,

Jordan testified that Gresham threatened to kill Taylor.            Finally,

in September 1995, Taylor left Gresham and moved into a mobile home

behind her parents' home, an apartment above an old gas station in

Alvord, Texas.

     In October 1995, Gresham offered a ride to a hitchhiker, Jimmy

Saville, and offered to hire him to torch a mobile home in Alvord.

Saville described the location of the mobile home, which was

located behind an old store with an upstairs residence.                  This

description   precisely     matched    the    address   of   Taylor's   home.

Saville declined the offer and reported the suspicious situation to

the Wise County sheriff's department.

     During the course of the next month, Gresham spoke often with

Anthony Odell, an employee of the Alvord Citgo Truck Stop. Gresham

claimed he was heartbroken over his separation from Taylor and

inquired whether Odell would burn down a residence in Alvord.

Odell    identified   the   residence        as   Taylor's   parents'   home.


                                      2
Furthermore, Gresham offered Odell $250 to deliver a package to the

mobile home located behind the residence.       In response to a query

from Odell, Gresham explained that the package contained a bomb.

Odell declined the offer.

     During this same period, Gresham was living in Odessa, Texas,

with his aunt, Dorothy Underwood, who testified that Gresham had

expressed his desire to take revenge on Taylor for leaving him.

Furthermore, Underwood testified that in November 1995, Gresham

built a pipe bomb in her home using gunpowder and component parts

purchased at Wal-Mart. When she confronted Gresham about the bomb,

he explained that he intended to bomb Taylor's parents' home.

Underwood protested this plan, and Gresham moved out of her house.

On December 31, 1995, Gresham called Underwood and warned her not

to discuss his activities while living with her, explaining that he

was about to take his revenge on Taylor.

     On the same day Gresham was building the pipe bomb in Odessa,

the post office in Seminole, Texas, received a change of address

order for “Cheryl Presley,” redirecting her mail from an address in

Seminole to an address in Odessa. “Cheryl Presley” was a pseudonym

occasionally used by Cheryl Taylor, and the address in Seminole

belonged   to   her   mother.   Subsequently,   Gresham   confessed   to

Underwood that he had redirected Taylor's mail from an address in

Seminole to a vacant house in Odessa, verifying his claim by

showing Underwood a letter addressed to Cheryl Taylor.

     Later that month, Gresham's son, Roger, learned that his

father had built a pipe bomb, and observed its detonation.       Roger


                                   3
subsequently guided investigators to the site of the blast, where

they discovered the charred remnants of an explosive device. Based

on their observations and an analysis of the component parts,

investigators concluded that a pipe bomb had exploded in the area.

     On December 8, 1995, Gresham attempted to hire a mechanic,

Robert Markle, to deliver a package to his ex-girlfriend's house.

Gresham bragged to Markle about his experience in such matters,

stating that he had “done this before.”   Markle declined the offer.

     Finally, by January 1996, Gresham's plot had reached fruition.

While attending an orientation for Southern Refrigerated Transport,

his new employer, Gresham confided in another driver, Michael Long.

Gresham stated that he and his girlfriend had recently separated,

and expressed his desire to take revenge against her. Furthermore,

Gresham recounted his plan to Long in excruciating detail.

     Gresham told Long he was going to mail his girlfriend a bomb,

using a United Parcel Service (“UPS”) label that had been prepared

by another individual.     To persuade her to open the package,

Gresham explained that he had redirected his girlfriend's mail and

intercepted a Christmas card addressed to her from a friend, which

he intended to package with the bomb like a Christmas present.

Long did not observe the card, but he did see a white envelope

addressed to Taylor.     Finally, Gresham showed Long the bomb, a

section of pipe with capped ends.    Gresham recanted the next day,

explaining that he had decided not to send the bomb, but he

threatened to harm Long and his family if Long repeated their

conversation.


                                 4
     Later in January, Gresham asked Roger to deliver a brown

cardboard box to Taylor, along with a photograph that he had

intercepted from Taylor's mail.       Gresham explained his plan to

package Taylor's mail with the box, to persuade her to open it.    In

addition, Gresham boasted that he could alter the entries in his

log book to “cover up his tracks.”     Roger refused to deliver the

package, and he attempted to dissuade his father from sending it to

Taylor.   Unfortunately, he failed.



                                B.

     On January 11, 1996, two unidentified men shipped a package to

Taylor from Sweetwater, Texas. Satellite tracking records obtained

from Southern Refrigerated Transport, Gresham’s employer, placed

Gresham in Sweetwater on that afternoon, although his log book did

not indicate a stop in Sweetwater.       The return address on the

shipping records identified the sender as Dana Meeks of Cedar

Creek, Texas; Meeks had mailed a Christmas card to Taylor during

the period when Taylor’s mail had been diverted.

     On January 12, U.P.S. delivered the package to Taylor.       The

package was a brown cardboard box attached to a Christmas card from

Meeks and a photograph of the Meeks family.        Taylor took the

package into her home and opened it, whereupon it exploded.       The

ensuing investigation led authorities to Gresham.



                                C.

     Gresham was arrested and charged, in a four-count indictment,


                                  5
with   possession      of   an   unregistered    firearm,   in     violation   of

§ 5861(d), and possession of a firearm by a convicted felon, in

violation of § 922(g)(1).          The government dismissed the other two

counts.     Gresham was convicted of both offenses.



                                       II.

       Gresham argues that the district court erred in denying his

motion to dismiss count one of the indictment, possession of an

unregistered       destructive      device,     because     the     statute     is

unconstitutional.        Alleging that the statute exceeds the taxation

power of Congress, Gresham claims that his conviction violates the

due process clause.         We disagree.



                                        A.

       Gresham argues that § 5861(d) is unconstitutional because it

exceeds the taxation power of Congress.           The National Firearms Act

(“NFA”), 26 U.S.C. § 5801 et seq., requires the payment of a tax on

the transfer or production of certain weapons.                    See 26 U.S.C.

§§ 5811, 5821.          In order to facilitate enforcement, the act

requires all firearms to be registered with the National Firearms

Registration and Transfer Record.            See 26 U.S.C. § 5841.      In order

to guarantee compliance with the registration requirement, the

statute criminalizes the possession of unregistered firearms.                  See

§ 5861(d).1

        1
            For purposes of the NFA, the term “firearm” includes “destructive
devices.”    See 26 U.S.C. § 5845(a). “Destructive devices,” in turn, include any
                                                                  (continued...)

                                        6
      Gresham charges that Congress has used the taxation power as

a pretext to prohibit the possession of certain disfavored weapons,

without any rational relationship to the revenue-raising purposes

of the Internal Revenue Code.           Therefore, Gresham claims that the

NFA confers a police power on the United States, antithetical to

the enumerated powers granted in the Constitution.

      To   the   contrary,   it    is   well-settled    that   §    5861(d)   is

constitutional because it is “part of the web of regulation aiding

enforcement of the transfer tax provision in § 5811.                    Having

required payment of a transfer tax and registration as an aid in

collection    of   that   tax,    Congress   under   the   taxing    power    may

reasonably impose a penalty on possession of unregistered weapons.”

United States v. Ross, 458 F.2d 1144, 1145 (5th Cir. 1972).2

      Insofar as the statute is a valid exercise of the taxing

power, the fact that it incidentally accomplishes goals other than

raising revenue does not undermine its constitutionality.               “[T]he

motives that move Congress to impose a tax are no concern of the

courts.”    Id. at 1146.     The facial constitutionality of 26 U.S.C.

§ 5861(d) is firmly established, and we need not reconsider it.



                                        B.

      Notwithstanding      the    statute's    facial      constitutionality,



(...continued)
“explosive bomb.” See 26 U.S.C. § 5845(f). Under this definition, the pipe bomb
manufactured by Gresham qualified as a “firearm” under the act.
      2
         See also United States v. Parker, 960 F.2d 498, 500 (5th Cir. 1992)
(discussing Ross).

                                         7
Gresham claims that his conviction violates the due process clause

and belies the constitutional foundation of § 5861(d), because it

was legally impossible for him to register the pipe bomb and thus

comply with the requirements of the NFA.                We disagree.

         The NFA forbids the manufacture or transfer of any firearm

without the government's advance permission.                 Permission shall be

denied if the making, transfer or possession of the firearm would

place the transferee in violation of the law.                     See 26 U.S.C.

§§ 5812, 5822.      If permission is not obtained, the registration

requirement     cannot   be    satisfied.         See   26   U.S.C.    §   5841(c).

Consequently, Gresham complains that the NFA permits the government

to deny registration, yet permits prosecution for possession of an

unregistered firearm.         This dilemma, he contends, violates the due

process clause and belies the constitutional foundation of the

statute.

         In support of this argument, Gresham cites two cases in which

convictions      obtained     pursuant       to   §   5861(d)   have   been   held

unconstitutional, under circumstances similar to the instant case.

See, e.g., United States v. Dalton, 960 F.2d 121 (10th Cir. 1992);

United States v. Rock Island Armory, Inc., 773 F. Supp. 117 (C.D.

Ill. 1991). These two courts held that a conviction for possession

of an unregistered machinegun, in violation of § 5861(d), would

violate due process because the enactment of another statute,

18 U.S.C. § 922(o), made registration of the firearms impossible.3

     3
       Section 922(o) outlaws the transfer or possession of all machineguns that
were not lawfully possessed prior to the effective date of the statute. Because
                                                                  (continued...)

                                         8
Likewise, they held that a statute enacted under the taxing power,

to facilitate the enforcement and collection of the tax, loses its

constitutional foundation when the object of the tax is prohibited.

See Dalton, 960 F.2d at 125; Rock Island Armory, 773 F. Supp. at

125.    Accordingly, the two courts concluded, it would violate due

process to convict a defendant for violations of a statute when

compliance with it is legally impossible.

       This court rejected the same claim in United States v. Ardoin,

19 F.3d 177 (5th Cir. 1994), holding that the enactment of § 922(o)

did not absolve machinegun owners of their obligation to register

such weapons and pay the tax as required by the NFA, nor did it

immunize them from criminal prosecution if they failed to comply

with   the   statute.      Id.   at   180.     Furthermore,     we   held   that

prosecutions under § 5861(d) are constitutional, despite the fact

that it is legally impossible to register machineguns in the wake

of § 922(o).      Id.   Hence, we held that such prosecutions do not

offend due process.4

       The Ardoin court based its conclusions on two fundamental




(...continued)
possession of machineguns manufactured or transferred after that date is illegal,
their registration is legally impossible. See 26 U.S.C. § 5812, 5822.
       4
         We declined to follow Dalton and Rock Island Armory in reaching our
decision in Ardoin. See Ardoin, 19 F.3d at 179-80. Furthermore, the majority
of courts addressing this question have agreed with our disposition, declining
to follow Dalton and Rock Island Armory. See United States v. Hunter, 73 F.3d
260, 261-62 (9th Cir. 1996); United States v. Rivera, 58 F.3d 600, 601-02 (11th
Cir. 1995); United States v. Ross, 9 F.3d 1182, 1192-94 (7th Cir. 1993), vacated
on other grounds, 511 U.S. 1124 (1994); United States v. Jones, 976 F.2d 176,
182-84 (4th Cir. 1992).

                                       9
premises that apply with equal force in the instant case.5                  First,

the       court   noted   that    Congress      may   tax    illegal     activity.6

Consequently,       although      §   922(o)    prohibits    the    transfer    and

possession of machineguns not legally possessed prior to 1986,

Congress may still tax the illegal possession of such machineguns

and may still assess criminal penalties for failure to comply with

the registration requirements promulgated to enforce the tax.                   Id.

Insofar as the basis for the authority to regulate compliance with

the registration requirementsSSthe taxing authoritySSstill exists,

the Ardoin court held that the registration requirements are

constitutional under the taxation power.              Id.

      Likewise, even if Gresham was not legally entitled to possess

a pipe bomb, the mere fact that his possession was illegal did not

absolve him of the obligation to comply with the requirements of

the NFA, nor did it preclude the government from prosecuting him

for his failure to register the destructive device.                 The pipe bomb

remained      taxable     under   the   NFA;    therefore,    the   registration

requirements        and    enforcement        provisions     of    the    NFA   are

constitutional and enforceable.            Cf. Ardoin, 19 F.3d at 180.

      Indeed, the facts of this case are even less sympathetic than


      5
        Gresham attempts to distinguish Ardoin by claiming that the only issue
in Ardoin was whether the enactment of § 922(o) had implicitly repealed portions
of the NFA. This distinction is superficial and unpersuasive, however, as the
theory of implicit repeal considered in Ardoin was based on the argument that the
ban on machineguns rendered the registration requirements and criminal penalties
of the NFA unconstitutional.     Ardoin, 19 F.3d at 179.       Therefore, Ardoin
necessarily decided the constitutional issue as a prerequisite to rejecting the
theory of implicit repeal. Id.
      6
       The authority of Congress to tax illegal activity is firmly established.
See, e.g., Department of Revenue v. Kurth Ranch, 511 U.S. 767, 778 (1994);
Marchetti v. United States, 390 U.S. 39, 44 (1968).

                                         10
are those we found insufficient to merit relief in Ardoin.               There,

registration of the machineguns was legally impossible, as the

object of the tax had been banned completely by § 922(o).                     No

federal statute completely outlaws the possession of pipe bombs,

however; therefore, their registration is not legally impossible.

United States v. Gambill, 912 F. Supp. 287, 290 (S.D. Ohio 1996);

accord United States v. Copus, 93 F.3d 269, 276 (7th Cir. 1996).7

      For this reason, the registration requirement governing pipe

bombs is not a mere pretext for a police power, but is “part of the

web of regulation aiding enforcement of the transfer tax provision

in § 5811.”     Ross, 458 F.2d at 1146.8        Under the circumstances of

the   instant   case,    therefore,    the   registration     requirement     is

plainly constitutional.

      Second, to the objection that it would violate due process to

convict a defendant for the possession of an unregistered firearm,

when such registration is impossible because the defendant cannot

legally possess the firearm, the Ardoin court had a ready answer:


          7
        See also United States v. Thomas, 15 F.3d 381, 382-83 (5th Cir. 1994)
(affirming the denial of a motion for acquittal under § 5861(d) because defendant
failed to demonstrate that pipe bombs cannot be registered).
      8
       Gresham offers no authority to support the proposition that registration
of a pipe bomb is legally impossible, but he contends that registration of a pipe
bomb is impossible as a practical matter. However true that may be, it does not
undermine the constitutional basis of the statute.         To the contrary, if
possession of pipe bombs is not illegal per se, the registration requirement is
reasonably related to the revenue purposes of the act and does not impose an
unreasonable dilemma on Gresham.
      We express no opinion as to whether the prohibition against possession of
a firearm by a convicted felon, 18 U.S.C. § 922(g)(1), would have been sufficient
to render the registration of the pipe bomb legally impossible in this case, as
Gresham does not suggest this alternative ground for our consideration. See
United States v. Rivera, 58 F.3d 600, 601-02 (11th Cir. 1995) (holding that the
prohibition against possession of a firearm by a convicted felon does not render
registration of such firearms “legally impossible”).

                                       11
Just say no.     If registration of the weapon is legally impossible,

we explained, the defendant can comply with the registration

requirement by not taking unlawful possession of an illegal weapon.

Therefore, we held that prosecutions for failure to comply with the

registration requirement do not violate the Due Process Clause,

notwithstanding the fact that compliance may be legally impossible,

because such prosecutions impose no “cruel dilemma” on defendants.

Ardoin, 19 F.3d at 180 n.4.

         Likewise, if it was legally impossible for Gresham to register

the pipe bomb and thereby comply with the NFA, he could avoid

prosecution by not engaging in the illegal activity.                If Gresham

chose to build an illegal pipe bomb and violate the law, therefore,

he   cannot    subsequently    complain      that   his   prosecution    for   a

violation of § 5861(d) offends the Due Process Clause.                There is

nothing “fundamentally unfair” about punishing a criminal, whether

directly or indirectly, for engaging in illegal activity.                    Cf.

Ardoin, 19 F.3d at 180 n.4.9




                                      III.

         Gresham next argues that the district court erred in denying


     9
       The mere fact that Gresham is exposed to prosecution for the same conduct
under two different criminal statutes does not occasion a constitutional defect.
The Constitution permits Congress to prohibit the same conduct under multiple
statutes, provided the prosecution does not violate the Double Jeopardy Clause.
See, e.g., Hunter, 73 F.3d at 262; Ross, 9 F.3d at 1194; Jones, 976 F.2d at 183.
In the instant case, Gresham's prosecution does not constitute double jeopardy.
Accordingly, the government is entitled to prosecute him under both statutes, and
the threat of prosecution under one statute does not immunize him from
prosecution under another.

                                       12
his motion      to     dismiss       count    two    of   the   indictment,    charging

possession of a firearm by a convicted felon in violation of

§ 922(g)(1), because that statute is unconstitutional.                             Citing

United States v. Lopez, 514 U.S. 549 (1995), Gresham claims the

statute      exceeds     Congress's          authority     to    regulate   interstate

commerce.     Furthermore, he argues that the indictment charging him

with violations of § 922(g)(1) was defective in that it failed to

charge every element of the offense.                  Neither claim has merit.



                                              A.

      The constitutionality of § 922(g)(1) is not open to question.

In United States v. Rawls, 85 F.3d 240 (5th Cir. 1996), we held

that “neither the holding in Lopez nor the reasons given therefor

constitutionally         invalidate          §     922(g)(1).”        Id.     at   242.10

Accordingly, Gresham’s constitutional challenge is foreclosed by

circuit precedent.



                                              B.

      Likewise, Rawls defeats Gresham’s challenge to the indictment.

Arguing that Lopez permits the United States to regulate intrastate

activities only if they “substantially affect” interstate commerce,

Gresham claims that the indictment was defective because it charged

him   with     possessing        a    firearm       “in   or    affecting   interstate

commerce,”      omitting         the     constitutional          requirement       of   a

      10
         See also United States v. Dickey, 102 F.3d 157, 163 (5th Cir. 1996)
(reaffirming Rawls); United States v. Kuban, 94 F.3d 971, 973 (5th Cir. 1996)
(reaffirming Rawls), cert. denied, 117 S. Ct. 716 (1997).

                                              13
“substantial effect.” Therefore, Gresham concludes, the indictment

did not charge every essential element of the offense, and must be

dismissed.    Not so.

      In Rawls, we recognized that the “in or affecting commerce”

element of § 922(g)(1) may be satisfied if the firearm possessed by

a convicted felon had traveled in interstate commerce.             See Rawls,

85 F.3d at 242-43.      Citing Scarborough v. United States, 431 U.S.

563 (1977), we further concluded that the statute requires only a

“minimal nexus” between the firearm and interstate commerce.                Id.

at 243-44 (Garwood, J., specially concurring).11           Consequently, the

court held that the jurisdictional nexus was satisfied in Rawls

because the firearm had traveled previously in interstate commerce.

Likewise, in the instant case the government offered evidence to

demonstrate that the firearm had traveled in interstate commerce,

thereby satisfying the jurisdictional nexus.

      Therefore, given that the “in or affecting commerce” element

of § 922(g)(1) requires only a “minimal nexus” between the firearm

and interstate commerce, the indictment in the instant case was not

defective    for   omitting    the    “substantial     effect”    requirement

endorsed in Lopez.      Gresham is entitled to no relief on this claim.



                                      IV.


     11
         The Rawls court acknowledged that this construction is at odds with the
restrictive interpretation of the interstate commerce power endorsed in Lopez,
but considered itself bound to follow the unambiguous language of Scarborough.
85 F.3d at 243 (Garwood, J., specially concurring). The Rawls interpretation of
the “in or affecting commerce” element of § 922(g)(1) is binding on this court.
Therefore, the jurisdictional nexus provision of § 922(g)(1) requires only a
“minimal nexus” between the firearm and interstate commerce.

                                      14
      Gresham avers that the evidence was insufficient to support

his conviction for possession of a firearm by a convicted felon,

under § 922(g)(1), because the evidence proved only that the

component parts of the pipe bomb, rather than the bomb itself, had

traveled in interstate commerce.             We disagree.



                                        A.

      In a sufficiency challenge, we examine the evidence in the

light most favorable to the verdict and reverse only if no rational

trier of fact could have found that the evidence established each

element of the offense beyond a reasonable doubt.12                  In order to

obtain a conviction under § 922(g)(1), the government must prove

three essential elements: (1) that the defendant previously had

been convicted of a felony; (2) that he possessed a firearm; and

(3) that the firearm traveled in or affected interstate commerce.

See United States v. Fields, 72 F.3d 1200, 1211 (5th Cir.), cert.

denied, 117 S. Ct. 48 (1996).           Gresham challenges only the third

prong.



                                        B.

      Gresham claims that the evidence was insufficient to support

his conviction because the evidence proved only that the component

parts of the pipe bomb traveled in interstate commerce.                   Indeed,

the evidence demonstrates that Gresham assembled the bomb in Texas


      12
         See, e.g., United States v. Walters, 87 F.3d 663, 667 (5th Cir.), cert.
denied, 117 S. Ct. 498 (1996); United States v. Dean, 59 F.3d 1479, 1484 (5th Cir.
1995), cert. denied, 116 S. Ct. 748 (1996), and cert. denied, 116 S. Ct. 794 (1996).

                                        15
and shipped it by private carrier from one Texas city to another.

Because the pipe bomb itself did not travel in interstate commerce,

therefore, Gresham contends that the evidence was insufficient to

support the conviction.        He is mistaken.

      The statute provides that it shall be unlawful for a convicted

felon to possess in or affecting commerce, inter alia, any firearm.

See § 922(g)(1).      The term “firearm” is defined to mean, inter

alia, “any destructive device.”         See 18 U.S.C. § 921(a)(3).        The

term “destructive device” is defined to include, inter alia,

any “explosive bomb.”     See 18 U.S.C. § 921(a)(4)(A)(I).        Likewise,

the term “destructive device” also includes “any combination of

parts either designed or intended for use in converting any device

into any destructive device described in subparagraph (A) or (B)

and from which a destructive device may be readily assembled.” See

18 U.S.C. § 921(a)(3)(C). Under the plain language of the statute,

therefore, the component parts of a destructive device constitute

“firearms,” for purposes of § 922(g)(1).

      Although we have not previously addressed this precise issue,

our holding that the jurisdictional nexus of § 922(g)(1) may be

satisfied by proof that the component parts of the firearm traveled

in interstate commerce, rather than the firearm itself, comports

with the construction of this statute endorsed by two of our sister

circuits.   See United States v. Verna, 113 F.3d 499, 502-03 (4th

Cir. 1997); United States v. Mosby, 60 F.3d 454, 456-57 (8th Cir.

1995), cert. denied, 116 S. Ct. 938 (1996).           Accordingly, we join

the   majority   of   courts    in   holding   that   component   parts   are


                                      16
“firearms” for purposes of § 922(g)(1).13

      The government offered the testimony of two expert witnesses

to establish that the component parts of the pipe bomb had been

manufactured     outside    Texas    and    had   necessarily     traveled    in

interstate commerce before being assembled by Gresham.14                Viewing

this evidence in the light most favorable to the verdict, a

reasonable jury could conclude that the component parts of the

destructive device had traveled in interstate commerce. Therefore,

because the component parts of a destructive device are “firearms,”

for purposes of § 922(g)(1), the evidence was sufficient to support

Gresham’s conviction under that section.



                                       V.

      Gresham argues that the district court erred in permitting the

government to introduce hearsay testimony to demonstrate that the

component parts of the bomb had traveled in interstate commerce.

The government introduced the testimony of two expert witnesses,


       13
          In a decision construing the predecessor to § 922(g)(1), the Second
Circuit held that the jurisdictional nexus element of 18 U.S.C. § 1202(a) was not
satisfied by proof that the process of manufacturing a firearm, including
transactions in component parts, had traveled in or affected interstate commerce.
See United States v. Travisano, 724 F.2d 341, 347-48 (2d Cir. 1983). Travisano
is incompatible with the plain language of the statute, however, and has been
criticized for taking “an unjustifiedly narrow view of the relevant commerce.”
Mosby, 60 F.3d at 456. Accordingly, we decline to follow Travisano, and we align
ourselves with those courts that have enforced the plain language of the statute.
See Verna, 113 F.3d at 502; Mosby, 60 F.3d at 456.
      14
         These components included PyrodexSSan explosive powderSStwo batteries,
and “end caps.” The government experts testified that each of these products was
manufactured outside Texas and had necessarily traveled in interstate commerce.
      In particular, Pyrodex is “designed or intended for use” in explosives,
and destructive devices may be “readily assembled” from such explosive powders.
Therefore, the Pyrodex is sufficient to satisfy the jurisdictional nexus required
by § 922(g)(1). See Verna, 113 F.3d at 502; Mosby, 60 F.3d at 457.

agents of the Bureau of Alcohol, Tobacco and Firearms (“ATF”), to

satisfy the jurisdictional nexus element required by § 922(g)(1).

It is firmly established in this circuit that such evidence is

admissible to prove that a firearm was “in or affecting commerce”

for purposes of § 922(g)(1).



                                   A.

       We review the admission of evidence for abuse of discretion.

See United States v. Loney, 959 F.2d 1332, 1340 (5th Cir. 1992).

Our review, accordingly, is highly deferential.



                                   B.

       Gresham claims that the district court abused its discretion

by permitting the government to offer hearsay testimony in order to

satisfy the jurisdictional nexus required by § 922(g)(1).         We have

consistently stated, however, that “[p]roof of the interstate nexus

to the firearm may be based upon expert testimony by a law

enforcement officer.”     United States v. Privett, 68 F.3d 101, 104

(5th    Cir.   1995),   cert.   denied,   116   S.   Ct.   1862   (1996).

Furthermore, it is axiomatic that expert opinions may be based on

facts or data of a type reasonably relied upon by experts in a

particular field, even if the sources are not admissible evidence.

FED. R. EVID. 703.      Consequently, the court did not abuse its

discretion by permitting the expert witnesses to testify on the

basis of hearsay.

       The two ATF specialists testified that the component parts of


                                   18
the pipe bomb had been manufactured outside Texas and had traveled

in interstate commerce.         The agents, who were admitted as experts,

based     their   testimony   on    discussions     with   the    manufacturers,

corporate literature and reference materials maintained by the ATF,

studies of distinctive markings on the products, and their personal

experience in law enforcement.          On the strength of this testimony,

the jury necessarily found that the component parts had traveled in

interstate commerce.

      We have regularly upheld such expert testimony against hearsay

challenges, holding that expert testimony is admissible to satisfy

the jurisdictional nexus required by § 922(g)(1).15               In the instant

case, the ATF experts relied on similar information.                Accordingly,

the district court did not abuse its discretion in admitting the

expert testimony to satisfy the jurisdictional nexus element.



                                       VI.

      Gresham contends that the district court abused its discretion

in denying his motion for new trial, claiming that newly discovered

evidence     undermines   the      integrity   of   the    jury   verdict.    We

disagree.

      At trial, the government offered the testimony of Meeks, who

stated that the return address on the envelope accompanying the

pipe bomb had been written in her handwriting.               Meeks's testimony


     15
         See, e.g., United States v. Wallace, 889 F.2d 580, 584 (5th Cir. 1989)
(distinctive markings and experience); United States v. Merritt, 882 F.2d 916,
920 (5th Cir. 1989) (manufacturer's markings on gun); United States v. Harper,
802 F.2d 115, 121 (5th Cir. 1986) (distinctive markings, trade publications, and
company catalogues).

                                        19
corroborated that of other government witnesses and supported the

government's theory that Gresham had diverted the mail to obtain an

innocuous return address for his deadly package.          Immediately

following the trial, Meeks recanted her testimony, stating that the

return address was not written in her handwriting.

       Gresham moved for a new trial, claiming newly discovered

evidence.     The district court denied the motion, however, finding

that the challenged testimony was not material to the outcome of

the trial. Gresham challenges this conclusion on appeal, insisting

that    the   handwriting   identification   was   intrinsic   to   the

government’s case.      Given the overwhelming evidence marshaled

against Gresham, however, his claim is without merit.



                                  A.

       We review the denial of a motion for new trial on the basis of

newly discovered evidence exclusively for an abuse of discretion.

See, e.g., United States v. Jaramillo, 42 F.3d 920, 924 (5th Cir.),

cert. denied, 115 S. Ct. 2014 (1995); United States v. MMR Corp.,

954 F.2d 1040, 1047 (5th Cir. 1992).     Such motions are disfavored

and are reviewed with great caution.     Jaramillo, 42 F.3d at 924;

United States v. Pena, 949 F.2d 751, 758 (5th Cir. 1991).

       In order to merit a new trial on the basis of newly discovered

evidence, the defendant must prove (1) that the evidence is newly

discovered and was unknown to him at the time of trial; (2) that

the failure to discover the evidence was not due to his lack of

diligence; (3) that the evidence is not merely cumulative, but is


                                  20
material; and (4) that the evidence would probably produce an

acquittal.     Jaramillo, 42 F.3d at 924; Pena, 949 F.2d at 758.

Unless all four elements are satisfied, the motion for new trial

must be denied.     Jaramillo, 42 F.3d at 924; Pena, 949 F.2d at 758.

Gresham cannot satisfy this strict burden of proof.



                                      B.

      The newly discovered evidence upon which Gresham relies is

Meeks's   recantation.       We   have     often    observed,     however,   that

“recanting    affidavits    and   witnesses        are   viewed   with   extreme

suspicion by the courts.”         Spence v. Johnson, 80 F.3d 989, 1003

(5th Cir.), cert. denied, 117 S. Ct. 519 (1996).16 The instant case

is no exception.       Hence, the district court did not abuse its

discretion in ruling that the newly discovered evidence did not

warrant a new trial.

      Gresham claims that the first two requirements of the test for

newly discovered evidence are necessarily satisfied in this case,

because Meeks did not recant her testimony until after the trial.

Although the evidence was unknown to Gresham at the time of trial,

however, the government claims that Gresham did not exercise due

diligence, because the defense did not cross-examine Meeks.                  Under

similar circumstances, we have concluded that the failure to verify

handwriting on an envelope, when the witness testified at trial

concerning the handwriting, constituted a lack of diligence.                  See

     16
        Accord May v. Collins, 955 F.2d 299, 314 (5th Cir. 1992); United States
v. Nixon, 881 F.2d 1305, 1311 (5th Cir. 1989); United States v. Adi, 759 F.2d
404, 408 (5th Cir. 1985).

                                      21
United States v. Fowler, 735 F.2d 823, 831 (5th Cir. 1984).

      In her recanting statement to the district court, Meeks stated

that she realized during her trial testimony that the handwriting

on the envelope was not her own, but she testified falsely because

the prosecutor expected her to verify the handwriting.17 Therefore,

defense counsel could have exposed her indecision by effectively

cross-examining the witness. Having failed to examine the witness,

the defense failed to exercise due diligence at trial.              Therefore,

Gresham cannot claim that the subsequent recantation constitutes

“newly discovered” evidence.         See Fowler, 735 F.2d at 831.

      More importantly, Gresham cannot satisfy the materiality and

prejudice requirements of the test for newly discovered evidence.

In order to merit a new trial, a defendant must demonstrate that

newly discovered evidence would probably result in an acquittal.

See MMR Corp., 954 F.2d at 1046; Nixon, 881 F.2d at 1311.               Gresham

claims that Meeks's testimony was critical to the prosecution,

providing a crucial link in the chain of circumstantial evidence

linking him to the package delivered to Taylor.              We disagree.

      The evidence incriminating Gresham was overwhelming.               First,

the government offered the testimony of several witnesses with whom

Gresham had discussed his intentions.          Gresham bragged that he had

diverted Taylor's mail and stolen a Christmas card addressed to

her, which he intended to use as an innocuous courier for his

package.    Meeks verified that she had sent a Christmas card and

       17
           There is no question that the prosecutor acted in good faith and
believed Meeks’s trial testimony to be truthful; Meeks did not recant until after
trial.

                                       22
family photograph to Taylor, and Taylor testified that the Meeks

Christmas card and family photograph were attached to the package.

Finally, the package was shipped via U.P.S. from Sweetwater, and

satellite records demonstrated that Gresham was in Sweetwater on

the date the package was shipped.               Under these circumstances,

Meeks's   recantation     would   not    have   altered    the   verdict;   the

evidence incriminating Gresham was too damning to overcome.

      Whether the return address on the envelope was written by Dana

Meeks is not material to the ultimate issue in this case: whether

Gresham was guilty of shipping the pipe bomb to Taylor.               Although

Meeks's testimony corroborated the government's theory of the case,

it was not necessary to obtain a conviction.               Thus, the “newly

discovered” evidence was cumulative, not material. Moreover, given

the   weight   of   the   evidence   amassed     against   Gresham,   Meeks's

recantation is not sufficient to raise a reasonable doubt.              Under

these circumstances, it is impossible to conclude that this “newly

discovered evidence” would probably result in an acquittal.                 See

MMR Corp., 954 F.2d at 1046; Nixon, 881 F.2d at 1311.
