Before BENTON, WOLLMAN, and GRASZ, Circuit Judges.
                         ____________

PER CURIAM.

      A jury found Pao Xiong guilty of being an inmate in possession of a prohibited
object—namely, a cell phone—in prison, in violation of 18 U.S.C. § 1791(a)(2).
Xiong appeals his conviction, challenging the sufficiency of the evidence and arguing
that the district court1 violated his Sixth Amendment right to present a defense by
refusing to allow a witness to testify. We affirm.

      The evidence presented at trial established that Correctional Officer Justin
Culver noticed Xiong in a cubicle with three other inmates. Xiong’s t-shirt was pulled
up over his head. Culver asked the other inmates to leave and performed a pat-down
search of Xiong. He felt an object in Xiong’s pocket that turned out to be a black and
blue cell phone. Culver also found several pieces of paper listing cell phones and
handwritten prices.

       Culver identified Xiong when Xiong returned to his own cubicle and retrieved
his identification card. Culver then filed a report regarding the incident. At trial,
Culver admitted that his report differed from his testimony. His report did not
mention that three other inmates were found in the same cubicle as Xiong, nor did it
state that Xiong was identified after he was searched. Culver testified that he had
omitted information from the report that he had deemed irrelevant to the offense.

       Prior to trial, Xiong gave the district court notice that he intended to call as a
witness Santos Flores-Avilles, a fellow inmate who had been in the cubicle with
Xiong when he was apprehended. The district court granted Xiong the opportunity
to voir dire Flores-Avilles outside the jury’s presence. Xiong asked Flores-Avilles if
he had been charged administratively with, pleaded guilty to, and been disciplined
internally for possessing the same phone that was at issue in Xiong’s trial. Flores-
Avilles responded “yes.” The government then asked Flores-Avilles if the phone
belonged to him, to which he answered “no.” When the government asked Flores-
Avilles if his pictures were on the phone, he conferred with his court-appointed
counsel and ultimately exercised his Fifth Amendment right to refuse to testify. The

District of Arkansas.

district court denied Xiong’s request to ask his earlier-posed question at trial,
concluding that allowing Flores-Avilles to testify without facing cross-examination
would be prejudicial to the government’s presentation of the case.

        Xiong argues that the evidence was insufficient to support his conviction
because the admitted inaccuracies in Culver’s incident report rendered his testimony
not credible. We review de novo the sufficiency of the evidence, viewing the evidence
in the light most favorable to the government, resolving conflicts in the government’s
favor, and accepting all reasonable inferences that support the verdict. United States
v. Parks, 902 F.3d 805, 814 (8th Cir. 2018).

       The government was required to prove (1) that Xiong was an inmate in federal
prison, (2) that he possessed a cell phone while in prison, and (3) that a cell phone is
a prohibited item in prison. 18 U.S.C. § 1791(a)(2). Xiong concedes that the first and
third elements were proven. He argues that the evidence was insufficient to prove his
possession because Culver lacked credibility and had a motive to lie in light of
Xiong’s status as a “nuisance” prisoner. He does not argue that Culver’s testimony,
if credible, failed to establish his possession of the phone. Our “role is not to reweigh
the evidence or to test the credibility of the witnesses, because questions of credibility
are the province of the jury.” Parks, 902 F.3d at 814-15 (quoting United States v.
Vanover, 630 F.3d 1108, 1116 (8th Cir. 2011) (per curiam)). Accordingly, we
conclude that Culver’s testimony was sufficient to support Xiong’s conviction.

       Xiong also argues that the court should have allowed him to call Flores-Avilles
as a witness at trial. We need not determine whether this constituted error because any
error was harmless. See United States v. Lundstrom, 880 F.3d 423, 440 (8th Cir.
2018) (“An evidentiary error is harmless if the record demonstrates that the
defendant’s substantial rights were unaffected and that the error ‘did not influence or
had only a slight influence on the verdict.’” (quoting United States v. Lewis, 483 F.3d
871, 875 (8th Cir. 2007))). The government was required to prove only that Xiong

                                           -3-
possessed the cell phone at the time of his apprehension, not that Xiong owned it or
had exclusively possessed it in the past. See 18 U.S.C. § 1791(a)(2). Flores-Avilles’s
potential testimony that he had been disciplined for using the same phone in the past
was irrelevant to the issue of Xiong’s later possession of that phone.

      The judgment is affirmed.
