Tyronne Benard Cooper, federal prisoner # 09210-035, appeals the district court’s dismissal of his 28 U.S.C. § 2241 petition on summary judgment. Cooper contends that the district court erred by not ordering the Bureau of Prisons (BOP) to award credit for that portion of Cooper’s state sentence that was served prior to the imposition of his federal sentence.

The Attorney General, through the BOP, determines what credit, if any, will be awarded to prisoners for time spent in custody prior to the commencement of their sentences. See United States v. Wilson, 503 U.S. 329, 331-32, 334, 112 S.Ct. 1351, 117 L.Ed.2d 593 (1992). The BOP correctly determined under 18 U.S.C. § 3585(b) that it may not award Cooper credit toward his term of imprisonment for any time he spent in official detention pri- *42 or to the commencement of his sentence that was credited against another sentence.

AFFIRMED.
