MEMORANDUM **

Former Washington state prisoner Cullen M. Hankerson appeals pro se from the district court’s summary judgment in his 42 U.S.C. § 1983 action alleging constitutional violations arising from the alleged failure to investigate a tort claim. We have jurisdiction under 28 U.S.C. § 1291. We review de novo. Marsh v. County of San Diego, 680 F.3d 1148, 1152 (9th Cir. 2012). We affirm.

The district court properly granted summary judgment on Hankerson § 1983 claims against defendant Pressel because Hankerson failed to raise a genuine dispute of material fact as to whether Pressel caused a deprivation of any federal or constitutional right in his handling of Han-kerson’s tort claim. See id. (elements of 42 U.S.C. § 1983 claim).

The district court properly granted summary judgment on Hankerson’s § 1983 claims against the Department of Risk Management because “state agencies are ... protected from suit under § 1983.” Wolfe v. Strankman, 392 F.3d 358, 364 (9th Cir. 2004).

The district court properly granted summary judgment on Hankerson’s retaliation claim against defendant Combo because Hankerson failed to raise a genuine dispute of material fact as to whether Combo took any adverse action against Hankerson for filing civil complaints. See Rhodes v. Robinson, 408 F.3d 559, 567-68 (9th Cir. 2005) (setting forth elements of a retaliation claim in the prison context).

The district court properly granted summary judgment regarding Hankerson’s RICO claims because Hankerson failed to allege facts sufficient to state plausible claims for relief. See Hebbe v. Pliler, 627 F.3d 338, 341-42 (9th Cir. 2010) (although pro se pleadings are to be liberally construed, a plaintiff still must present factual allegations sufficient to state a plausible claim for relief).

The district court did not abuse its discretion in denying Hankerson’s motions for leave to amend his complaint to add additional defendants and claims. See Eminence Capital, LLC v. Aspeon, Inc., 316 F.3d 1048, 1051-52 (9th Cir. 2003) (setting forth standard of review and factors for permitting leave to amend).

We reject as unsupported by the record Hankerson’s contentions concerning judicial bias, discovery issues, and collusion between defense counsel and the district court.

We do not consider matters not specifically and distinctly raised and argued in the opening brief. See Padgett v. Wright, 587 F.3d 983, 985 n.2 (9th Cir. 2009).

AFFIRMED.
