Lewis Thomas Cornell seeks to appeal the district court’s order adopting the magistrate judge’s report and recommendation and dismissing his 28 U.S.C. § 2255 (2000) motion. Cornell cannot appeal this order unless a circuit judge or justice issues a certificate of appealability, and a certificate of appealability will not issue *607absent a “substantial showing of the denial of a constitutional right.” 28 U.S.C. § 2253(c)(2) (2000). A habeas appellant meets this standard by demonstrating that reasonable jurists would find that his constitutional claims are debatable and that any dispositive procedural rulings by the district court are also debatable or wrong. See Miller-El v. Cockrell, 537 U.S. 322, 326, 123 S.Ct. 1029, 154 L.Ed.2d 931 (2003); Slack v. McDaniel, 529 U.S. 473, 484, 120 S.Ct. 1595, 146 L.Ed.2d 542 (2000); Rose v. Lee, 252 F.3d 676, 683 (4th Cir. 2001). We have independently reviewed the record and conclude Cornell has not made the requisite showing. Accordingly, we deny a certificate of appealability and dismiss the appeal.

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
