MEMORANDUM **

Arizona state prisoner Donnie Romone Twiggs appeals pro se from the district court’s judgment dismissing his -42 U.S.C. § 1983 action alleging excessive force and other claims in connection with his arrest. *622 We have jurisdiction under 28 U.S.C. § 1291. We review de novo a dismissal under 28 U.S.C. § 1915A. Resnick v. Hayes, 218 F.3d 443, 447 (9th Cir. 2000). We affirm.

We affirm the district court’s dismissal of the action because Twiggs failed to raise any argument in his opening brief concerning any claim alleged in the operative complaint. See Smith v. Marsh, 194 F.3d 1045, 1052 (9th Cir. 1999) (“[AJrguments not raised by a party in its opening brief are deemed waived.”).

We reject Twiggs’s arguments related’to striking testimony because no testimony was before the district court in this action.

All pending motions are denied.

AFFIRMED.
