MEMORANDUM **
California state prisoner Charles Edward Allen appeals pro se from the district courts judgment dismissing his 42 U.S.C. § 1983 action alleging violations of the First and Eighth Amendments arising from alleged retaliation by a correctional officer. We have jurisdiction under 28 U.S.C. § 1291. We review de novo. Byrd v. Maricopa County Bd. of Supervisors, 845 F.3d 919, 922 (9th Cir. 2017) (dismissal under 28 U.S.C. § 1915A); Barren v. Harrington, 152 F.3d 1193, 1194 (9th Cir. 1998) (order) (dismissal under 28 U.S.C. § 1915(e)(2)(B)(ii)). We affirm.
The district court properly dismissed Allens First Amendment claim because Allen failed to allege facts sufficient to state a plausible claim. See Hebbe v. Pliler, 627 F.3d 338, 341-42 (9th Cir. 2010) (although pro se pleadings are to be liberally construed, a plaintiff must present factual allegations sufficient to state a plausible claim for relief); Rhodes v. Robinson, 408 F.3d 559, 567-68 (9th Cir. 2005) (elements of a First Amendment retaliation claim).
On appeal, Allen fails to address the district courts dismissal of his Eighth Amendment claims and has therefore waived his challenge to the district courts order regarding those claims. 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 appellants opening brief.”).
AFFIRMED.
