MEMORANDUM **

Prisoner Clarence Gipbsin appeals pro se the district court’s judgment in favor of defendant Walker following a jury trial in Gipbsin’s action alleging excessive use of force. We have jurisdiction under 28 U.S.C. § 1291, and we affirm.

Gipbsin has waived the claims he raises on appeal because he does not show that he raised them before the district court, *599 nor does he support them with any analysis, legal argument, citation to authority, or record evidence. To preserve an issue for appeal, the appellant must show that he raised that issue before the district court. Tennison v. Circus Circus Enters., Inc., 244 F.3d 684, 689 (9th Cir. 2001). The appellant must also do more in his briefing than summarily assert that the district court erred. Sekiya v. Gates, 508 F.3d 1198, 1200 (9th Cir. 2007); Indep. Towers of Wash. v. State of Wash., 350 F.3d 925, 929-30 (9th Cir. 2003).

Here, Gipbsin makes no showing that he raised any of his appellate issues at trial. Nor does he make any assertions of district court error that are specific enough for us to review. The issues he raises on appeal are therefore waived.

AFFIRMED.
