MEMORANDUM **

George C. Chatman appeals pro se from the district court’s judgment dismissing his action alleging that defendants violated his constitutional rights and committed various torts against him by instructing him to file tax returns for the years 2010, 2011, and 2012. We have jurisdiction under 28 U.S.C. § 1291. We affirm.

Chatman failed to address any of the district court’s grounds for dismissal, and has therefore waived his appeal of the district court’s order. See Indep. Towers of Wash. v. Washington, 350 F.3d 925, 929 (9th Cir. 2003) (“[W]e will not consider any claims that were not actually argued in appellant’s opening brief.”); Acosta-Huerta v. Estelle, 7 F.3d 139, 144 (9th Cir. 1993) (issues not supported by argument in pro se appellant’s opening brief are waived).

AFFIRMED.
