PER CURIAM:
Nevyou Alemu appeals his conviction after a bench trial for conspiracy to possess stolen firearms and aiding and abetting the possession of stolen firearms, in violation of 18 U.S.C. §§ 2, 371, 922Q), 924(a)(2) (2012). Alemu’s only assertion on appeal is that the district court erred in refusing to admit into evidence a disc containing audio recordings of his related state court proceedings.
This Court reviews a district court’s evi-dentiary rulings for abuse of discretion. United States v. Medford, 661 F.3d 746, 751 (4th Cir. 2011). Thus, we “afford[ ] the evidentiary ruling substantial deference, and will not overturn the ruling unless the decision was arbitrary and irrational.” Id. (internal quotation marks omitted). Our review of the record reveals no abuse of the district court’s discretion in excluding the evidence under Fed. R. Evid. 608(b).
Accordingly, we affirm the district court’s judgment. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.
AFFIRMED
