Actor and former California Gov. Arnold Schwarzenegger - who clapped back hard when President Donald Trump criticized his "Celebrity Apprentice" ratings via Twitter - shared in a recent social media post what his future political plans are.

He's not running for the Senate, but instead will seek to propel change as a concerned citizen.

"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," he posted. "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. Thank you for your kind messages and all of the support and I hope you'll join me in my battle against gerrymandering with the same enthusiasm."

Schwarzenegger, shown above in a publicity still from the 2014 movie "Sabotage," which was filmed in Atlanta, has been active in political matters despite his decision not to run. Here he is with Ohio Gov. and past presidential candidate John Kasich:

He's also gotten into some Twitter tit for tat with the president, his fellow "Celebrity Apprentice" alum, over matters of not-exactly national importance. Here's his response after Trump called his ratings bad and pathetic:
