Penn appeared on Ferguson’s show Thursday night to plug the appearance, and talked about his plans to help with President’s Obama’s campaign while balancing politics with his acting jobs.

“So, you’re out of politics completely then, that’s it?” Ferguson asked.

“I think so. I wanted to do about two years, I’d like to work on the president’s re-election,” Penn explained.

Ferguson pressed: “Are you going to go back and help with the campaign, then?”

“Yeah, I hope so,” Penn responded.

“It’s got to be a little trickier in the re-election campaign,” Ferguson noted. “Before you do the job, everyone’s like, ‘Oh, he’ll be great at it!’ And then you do it for a couple years and everyone goes, ‘Hey...where’s the money?’”

Other facts learned: Penn was in Washington for the earthquake on Tuesday; he only lived about a mile from the White House; it was tough for the actor to get to the gym while sitting at a desk all day in Washington.
