Jabar Eugene Currenee appeals the sentence imposed following his plea of guilty to one count of assaulting a correctional officer. Finding no error, we affirm.

Currenee first complains that the district court erred in denying him an adjustment for acceptance of responsibility. We review the district court’s determination under a highly-deferential standard. See United States v. Cano-Guel, 167 F.3d 900,[*463] 906 (5th Cir.1999). Given Currence’s improper, disrespectful and unlawful behavior during the presentence interview with the probation officer, the district court committed no error in denying the adjustment.

Currence also argues that the district court violated his Sixth Amendment rights in light of United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), by applying an adjustment for physical contact under U.S.S.G. § 2A2.4(b)(l), and for his status as a career offender under U.S.S.G. § 4B1.1. As Currence was sentenced after the decision in Booker was rendered, the district court was free to make all findings relevant to sentencing by a preponderance of the evidence. See United States v. Mares, 402 F.3d 511, 519 (5th Cir.), cert. denied, — U.S. -, 126 S.Ct. 43, 163 L.Ed.2d 76 (2005). Currence concedes that Mares is controlling, but he argues that it was incorrectly decided. We disagree and, in any event, we are bound by our precedent. See United States v. Stone, 306 F.3d 241, 243 (5th Cir.2002).

The judgment of the district court is AFFIRMED.
