AMENDED MEMORANDUM **

Robert Bianchi (“Bianchi”), a lieutenant at the Nevada State Prison with the Nevada Department of Corrections (“NDOC”), appeals the summary judgment dismissal of his § 1983 action, alleging that he was retaliated against by the NDOC in violation of his First Amendment rights. We have jurisdiction under 28 U.S.C. § 1291, and affirm.

Bianchi contends that NDOC demoted him in retaliation for his involvement in a no-confidence petition regarding the Assistant Warden of Operations, Walter Donat, and issued him a letter of reprimand in retaliation for testifying regarding the petition at a trial. However, Bianchi successfully appealed each disciplinary action, was reinstated to his former rank as a lieutenant, and the letter of reprimand was removed from his file. NDOC alleges that it had legitimate reasons for reprimanding Bianchi: he had failed to report on or properly supervise a misbehaving subordinate, and had misused a sick day and had given misleading statements about it.

Reviewing the grant of summary judgment de novo, we conclude Bianchi has not provided evidence sufficient to show any genuine issue of material fact. Retaliation claims against government employers must be supported by proof that protected speech was a “substantial or motivating factor in the adverse employment action.” *690 Eng v. Cooley, 552 F.3d 1062, 1070-72 (9th Cir. 2009). To do so, a plaintiff must first present evidence the defendant had knowledge of the plaintiffs protected speech. Alpha Energy Savers, Inc. v. Hansen, 381 F.3d 917, 928 (9th Cir. 2004) (citing Keyser v. Sacramento City Unified Sch. Dist., 265 F.3d 741, 750-52 (9th Cir. 2001)). Bianchi relies on allegations in his complaint as well as in his affidavit — conclusory, self-serving, and lacking any supporting evidence — which fail to establish a genuine issue of material fact on summary judgment review. F.T.C. v. Publ’g Clearing House, Inc., 104 F.3d 1168, 1171 (9th Cir. 1997) (citations omitted).

AFFIRMED.
