Dismissed by unpublished PER CURIAM opinion.

Unpublished opinions are not binding precedent in this circuit.

Alton Benn seeks to appeal the district court’s order affirming the magistrate judge’s denial of Benn’s motion to expand the record in his 28 U.S.C. § 2255 (2012) proceedings. This court may exercise jurisdiction only over final orders, 28 U.S.C. § 1291 (2012), and certain interlocutory and collateral' orders, 28 U.S.C. § 1292 (2012); Fed.R.Civ.P. 54(b); Cohen v. Beneficial Indus. Loan Corp., 337 U.S. 541, 545-46, 69 S.Ct. 1221, 93 L.Ed. 1528 (1949). The order Benn seeks to appeal is neither a final order nor an appealable interlocutory or collateral order. Accordingly, we dismiss the appeal for lack of jurisdiction. 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.

DISMISSED.
