Stephen Provencio, federal inmate # 28915-180, appeals the denial of his motion for 28 U.S.C. § 2255 relief, in which he challenged his guilty plea conviction for possession with intent to distribute 3, 4-methylenedioxymethamphetamine. The district court granted a certificate of appealability (COA) on whether United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), applied retroactively to Provencio’s § 2255 motion. The Government moves for summary affirmance in lieu of filing a brief or for an extension of time to file an appellate brief should the court deny its motion for summary affirmance.

Booker does not apply retroactively to Provencio’s § 2255 motion. See United States v. Gentry, 432 F.3d 600, 604-05 (5th Cir. 2005). Provencio’s argument that the district court violated his due process rights when it denied him a three-level reduction for acceptance of responsibility is outside the scope of the district court’s grant of a COA, and this court has already denied a COA on this issue. See Lackey v. Johnson, 116 F.3d 149, 151 (5th Cir. 1997).

The judgment of the district court is AFFIRMED. The Government’s motion for summary affirmance is GRANTED; the Government’s motion for an extension *145 of time to file an appellate brief is DENIED.
