Preston Joseph Robinson pleaded guilty pursuant to a written plea agreement to possession with intent to distribute five grams or more but less than 50 grams of cocaine base. He was sentenced to 110 months of imprisonment, four years of supervised release, and a $100 special assessment.

Robinson argues for the first time on appeal that the district court erred by *260 including, pursuant to the relevant conduct provision of U.S.S.G. § lB1.3(a)(2), an additional 15.4 grams of cocaine base in the calculation of his base offense level because the finding of the additional drug amount was made by the district court and was not made by a jury or admitted by Robinson. He contends that, in light of the Supreme Court’s decision in Blakely v. Washington, — U.S.-, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004), the use of the court’s finding of the additional drug amount in the determination of his sentence violates the Fifth and Sixth Amendments. As Robinson acknowledges, this issue is foreclosed. See United States v. Pineiro, 377 F.3d 464, 473 (5th Cir. 2004), petition for cert. filed (U.S. July 14, 2004) (No. 04-5263).

AFFIRMED.
