Shots fired: Arnold Schwarzenegger responded to Donald Trump's insult about his Apprentice ratings on Twitter, mere hours after Trump mocked the actor and former California governor at the National Prayer Breakfast in Washington D.C. on Thursday, February 2.

While appearing at the National Prayer Breakfast, an annual event designed to strengthen bonds between world leaders and business, technology, social and political leaders, Trump decided to burn a few bridges instead, in particular focusing on Schwarzenegger, who spoke out against the president's immigration ban on Monday.

"We had tremendous success on The Apprentice. And when I ran for president, I had to leave the show," Trump said. "That's when I knew for sure I was doing it. And they hired a big, big movie star—Arnold Schwarzenegger—to take my place, and we know how that turned out. The ratings went right down the tubes. It's been a total disaster... And I wanna just pray for Arnold if we can, for those ratings."

The Terminator icon quickly hit back on Twitter, posting a short video with an offer to trade jobs with Trump.

"Hey Donald, I have a great idea," Schwarzenegger says in the clip. "Why don't we switch jobs? You take over TV, because you're such an expert at ratings, and I take over your job, and then people can finally sleep comfortably again. Hmm?"
