(CNN) Former California Gov. Arnold Schwarzenegger shared his frustrations about how "nothing is getting done" in American politics on CNN's "The Axe Files," airing Saturday at 7p.m. ET on CNN.

"I'm very little interested in politics, because it sucks," he said when asked about President Trump's choice to focus his midterm platform on the economy, the confirmation of Justice Brett Kavanaugh to the Supreme Court, and the northward march of migrants in Central America. "I'm more interested in policy."

Schwarzenegger said he found America's lack of immigration policy reform and crumbling infrastructure particularly embarrassing. "For 20 years, they have promised to create immigration reform and they haven't," he told host David Axelrod. "To me, it's more important to get the job done rather than ... worry about a caravan coming or not."

According to Schwarzenegger, this stagnation and the United States' general "atmosphere of extremism" can be traced back to gerrymandering, an

issue he's publicly spoken out against in recent years. He explained how with gerrymandering, each party is "locked in" to a district and is essentially unbeatable. "When the far right and the far left go to the capitol, be it the state capitol or in Washington, they cannot get together," he said. Schwarzenegger recently campaigned for redistricting initiatives in Colorado and Michigan.
