Arnold Schwarzenegger is dismissing rumors of a 2018 Senate run in a Sunday Facebook post, saying his current priority is redistricting reform.

“I’m deeply flattered by all of the people who have approached me about running for Senate, but my mission right now is to bring sanity to Washington through redistricting reform like we passed here in California,” the actor and former Republican California governor wrote.

“Gerrymandering has completely broken our political system and I believe my best platform to help repair it is from the outside, by campaigning for independent redistricting commissions,” he continued.

Politico first reported that the former actor could be considering a Senate run.

Despite his Facebook post, Schwarzenegger spokesman Daniel Ketchell did not directly reject a possible Senate bid.

“Right now Gov. Schwarzenegger’s focus is on using his platform to bring some sensibility and coherency to Washington by fighting for redistricting reform, like we did in California. We are keeping all of our options open as far as how we can accomplish that,” Ketchell told Politico in an email on Thursday.

Schwarzenegger's response to critical tweets from President Trump likely fed into the buzz about a political run.

When Trump slammed Schwarzenegger, his successor as host of “The Celebrity Apprentice,” for “bad ratings,” Schwarzenegger posted a video suggesting they swap jobs.

Schwarzenegger quit his "Apprentice" role earlier this month, citing “baggage” as a reason for his departure.

Trump, however, suggested in a tweet that Schwarzenegger was fired.

Politico reports that Republicans talked about the possibility of Schwarzenegger running partly because he would challenge the longtime Democratic incumbent in California, Sen.

“[It] would give Arnold the stage to jam Trump for the next 16 months,’’ one GOP strategist told Politico.
