Gregory Swecker appeals from the district court’s 1 order granting defendant’s motion to dismiss under Federal Rule of Civil Procedure 12(b)(1). Following careful de novo review, see Green Acres Enters., Inc. v. United States, 418 F.3d 852, 856 (8th Cir. 2005), we agree that dismissal of Swecker’s complaint was proper for the reasons stated by the district court. Accordingly, we affirm. See 8th Cir. R. 47B.
