Federal inmate Joe Butler appeals the district court’s 1 denial without prejudice of his petition for a writ of habeas corpus, filed under 28 U.S.C. § 2241. Upon careful review, we conclude the court did not abuse its discretion in denying relief for failure to exhaust administrative remedies. See Kendrick v. Carlson, 995 F.2d 1440, 1447 (8th Cir. 1993) (standard of review). We affirm. See 8th Cir. R. 47B.
