George Dodge appeals his sixty-month sentence imposed following his guilty plea to threatening to assault and murder an Assistant United States Attorney with the intent to retaliate against her on account of the performance of her official duties, in violation of 18 U.S.C. § 115(a)(1)(B) (2000). On appeal, the sole issue raised by Dodge is whether the district court erred in calculating his guideline range by denying him a reduction for acceptance of responsibility. * We affirm.

In order to receive a reduction pursuant to U.S. Sentencing Guidelines Manual (“USSG”) § 3E1.1 (2003), “the defendant must prove by a preponderance of the evidence that he has clearly recognized and affirmatively accepted personal responsibility for his criminal conduct.” United States v. May, 359 F.3d 683, 693 (4th Cir. 2004) (citing United States v. Note, 101 F.3d 1000, 1005 (4th Cir. 1996)). We review a district court’s decision to grant or deny an adjustment for acceptance of responsibility for clear error. United States v. Ruhe, 191 F.3d 376, 388 (4th Cir. 1999). Based on our review of the record, including Dodge’s filings and testimony, we find no clear error in the district court’s finding that Dodge failed to accept responsibility for his criminal conduct. *219 See USSG § 3E1.1, comment. (n.l(a)) (“[A] defendant who falsely denies, or frivolously contests, relevant conduct that the court determines to be true has acted in a manner inconsistent with acceptance of responsibility.”).

Accordingly, we affirm Dodge’s sentence. 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.
