Thomas Cleveland, federal prisoner #41758-179, appeals the district court’s denial of his 28 U.S.C. § 2241 petition. Cleveland argues that the district court erred by concluding that the Bureau of Prisons (BOP) correctly denied him pre-sentence credit against his federal sentence for the time he spent in state custody between December 15, 2004, and April 30, 2006.

A defendant is given credit toward his term of imprisonment for any time he spent in official detention prior to the commencement of his sentence “that has not been credited against another sentence.” 18 U.S.C. § 3585(b). Here, the period for which Cleveland seeks credit against his federal sentence was credited against his state sentence. Thus, the BOP properly determined that Cleveland was not entitled to credit under § 3585(b) against his federal sentence. The judgment of the district court is therefore AFFIRMED.
