2                      UNITED STATES v. ALLEN
                              OPINION

PER CURIAM:

   Shawn Lee Allen appeals his conviction and 151-month sentence
for conspiracy to distribute more than fifty grams of cocaine base, in
violation of 21 U.S.C. § 846 (2000).

   Allen first challenges the sufficiency of the evidence supporting his
conspiracy to distribute cocaine base conviction. He argues that no
physical evidence such as drugs, photographs, tapes, or fingerprints
were presented at trial, and therefore the evidence is insufficient.
However, physical evidence is not required to prove involvement in
a drug distribution conspiracy. Allen’s coconspirators testified to
Allen’s involvement in drug transactions spanning several years. Fur-
thermore, a drug conspiracy is often proven entirely by such circum-
stantial evidence. See United States v. Burgos, 94 F.3d 849, 857 (4th
Cir. 1996).

  Allen also contends the district court demonstrated bias against
him. However, he has presented no evidence of any improper state-
ments or conduct by the district court.

  Accordingly, we affirm Allen’s conviction and sentence. We dis-
pense with oral argument because the facts and legal contentions were
adequately presented in the materials before the court.
