MEMORANDUM *

Plaintiff Rigoberto Cardenas, Jr. appeals the district court’s grant of summary judgment in favor of defendant United Parcel Service, Inc. (“UPS”) on his federal retaliatory termination and state-law wrongful discharge claims. The district court based its grant of summary judgment on two grounds: (1) plaintiffs claims were preempted by the National Labor Relations Act, and (2) even if they were not preempted, plaintiff failed to make out a prima facie case on either claim sufficient to survive summary judgment. We affirm.

“[W]e may affirm the district court’s ruling on the merits ‘on any ground supported by the record.’ ” Heinemann v. Satterberg, 731 F.3d 914, 918 (9th Cir. 2013) (quoting Van Asdale v. Int’l. Game Tech., 577 F.3d 989, 994 (9th Cir. 2009) (internal quotation marks omitted)). We agree with the district court’s conclusion that plaintiff failed to make out a prima facie case of retaliatory discrimination under federal law or wrongful termination under state law. We therefore need not reach the question of preemption, and express no views as to the district court’s conclusions on that issue.

AFFIRMED.
