James E. Thompson, Sr., appeals the district court’s 1 dismissal of his civil action without prejudice for lack of subject matter jurisdiction. Upon careful review of the record, we conclude that Thompson established neither diversity jurisdiction nor federal-question jurisdiction. See 28 U.S.C. §§ 1331, 1332(a)(1); 4:20 Communications, Inc. v. Paradigm Co., 336 F.3d 775, 779 (8th Cir. 2003) (party invoking federal jurisdiction has burden to establish jurisdictional requirements). Accordingly, we affirm. See 8th Cir. R. 47B. We also deny Thompson’s pending motion.
