    Submitted: January 30, 2018
    Decided: February 1, 2018
    Antonio Mosley, Appellant Pro Se. William Michael Miller, Melissa Louise Ri-kard, Assistant United States Attorneys, Ann Claire H. Phillips, OFFICE OF THE UNITED STATES ATTORNEY, Charlotte, North Carolina; Amy Elizabeth Ray, Assistant United States Attorney, OFFICE OF THE UNITED STATES ATTORNEY, Asheville, North Carolina, for Appellee.
    Before MOTZ and KEENAN, Circuit Judges, and HAMILTON, Senior Circuit Judge.
   Unpublished opinions are not binding precedent in this circuit.

PER CURIAM: '

Antonio Mosley seeks to appeal the district court’s order denying relief on his 28 U.S.C. § 2255 (2012) motion. The order is not appealable unless a circuit justice or judge issues a certificate of appealability. 28 U.S.C. § 2253(c)(1)(B) (2012). A certificate of appealability will not issue absent “a substantial showing of the denial of a constitutional right.” 28 U.S.C. § 2253(c)(2) (2012). When the district court denies relief on the merits, a prisoner satisfies this standard by demonstrating that reasonable jurists would find that the district court’s assessment of the constitutional claims is debatable or wrong. Slack v. McDaniel, 529 U.S. 473, 484, 120 S.Ct. 1595, 146 L.Ed.2d 542 (2000); see Miller-El v. Cockrell, 537 U.S. 322, 336-38, 123 S.Ct. 1029, 154 L.Ed.2d 931 (2003). When the district court denies relief on procedural grounds, the prisoner must demonstrate both that the dispositive procedural ruling is debatable, and that the motion states a debatable claim of the denial of a constitutional right. Slack, 529 U.S. at 484-85, 120 S.Ct. 1595.

We have independently reviewed the record and conclude that Mosley has not made the requisite showing. Accordingly, although we grant Mosley’s motion for leave to file a supplemental informal brief, we deny a certificate of appealability and dismiss the appeal. We deny Mosley’s motions for bail or release pending appeal, for appointment of counsel, and to hold the Government in default for failure to respond. 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
