Federal inmate Thomas Ginn appeals the district court’s 1 denial of his 28 U.S.C. § 2241 petition in which he requested federal sentence credit for time that he spent in custody from January 20, 2010, through September 12, 2013. Upon careful de novo review, see Mitchell v. United States Parole Comm’n, 538 F.3d 948, 951 (8th Cir. 2008), we agree with the district court’s reasoning and conclusion that habeas relief was not warranted. Accordingly, the judgment is affirmed. See 8th Cir. R. 47B.
