Derrick Estell directly appeals after he pled guilty to two counts of brandishing a firearm in furtherance of a crime of violence, and the district court 1 sentenced him to 32 years in prison. His counsel has moved to withdraw, and has filed a brief under Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), arguing that Estell’s prison term is substantively unreasonable. 2

*600 Upon careful review, we conclude that counsel’s argument lacks merit because Estell’s prison term, representing the statutory minimum, is not subject to review for reasonableness. See United States v. Gregg, 451 F.3d 930, 937 (8th Cir. 2006). Furthermore, having independently reviewed the record pursuant to Penson v. Ohio, 488. U.S. 75, 109 S.Ct. 346, 102 L.Ed.2d 300 (1988), we find no nonfrivo-lous issues. Accordingly, we grant counsel’s motion to withdraw, and we affirm.
