Michael G. Keselica seeks to appeal the district court’s order dismissing his petition under 28 U.S.C. § 2241 (2000). We have independently reviewed the record and conclude that Keselica has not made a substantial showing of the denial of a constitutional right. See Miller-El v. Cockrell, 537 U.S. 322, 336, 123 S.Ct. 1029, 154 L.Ed.2d 931 (2003). Accordingly, we deny Keselica’s motions to supplement the record and for a certificate of appealability and dismiss the appeal. See 28 U.S.C. § 2253(c) (2000). We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

DISMISSED
