Exdonovan Peak, federal prisoner # 08770-005, appeals the district court’s denial of his 18 U.S.C. § 3582(c) motion to reduce the 365-month sentence imposed following his conviction for conspiracy to possess with intent to distribute cocaine. Peak sought a reduction in sentence pursuant to the amendments to the Sentencing Guidelines for crack cocaine. The district court determined that Peak did not *620 qualify for a reduction because his offense involved over 4.5 kilograms of crack cocaine. See U.S.S.G. § 2D1.1, comment. (n.lO(D)(ii)(I)). Peak argues that he qualified for a two-level reduction in his base offense level because his offense involved less than 4.5 kilograms of crack cocaine and that the district court’s reliance on the estimate in the presentence report that the conspiracy involved 16 kilograms of crack cocaine was insufficient.

Although the district court’s decision whether to reduce a sentence ordinarily is reviewed for an abuse of discretion, we review the court’s interpretation of the Guidelines de novo and its factual findings for clear error. United States v. Doublin, 572 F.3d 235, 237 (5th Cir. 2009), cert. denied, — U.S. —, 130 S.Ct. 517, — L.Ed.2d — (2009); United States v. Mimms, 43 F.3d 217, 220 (5th Cir. 1995). Because the trial evidence supports the district court’s finding that the amount of crack cocaine involved in the offense exceeded 4.5 kilograms, the district court did not err in denying Peak’s motion for a reduction of sentence. See U.S.S.G. § 2D1.1, comment. (n.l0(D)(ii)(I)).

AFFIRMED.
