And now this: Donald Trump mocked Arnold Schwarzenegger’s ratings for The New Celebrity Apprentice during the National Prayer Breakfast — and the actor is firing back.

The annual D.C. event usually has about 3,500 guests from around the world and is run by a Christian organization. As is tradition, the president gives a keynote speech along with an outside speaker (at President Obama’s first National Prayer Breakfast in 2009, he had British Prime Minister Tony Blair, for example).

Trump had The Apprentice executive producer Mark Burnett and his wife Roma Downey as his speakers. In the video below, first Trump assured senate chaplain Barry Black that he won’t be fired from his position even if he’s a Democrat. Then he thanked Burnett and Downey for their “introduction.” — which inextricably led Trump to the subject of his former NBC show’s ratings under new host Arnold Schwarzenegger.

“When I ran for president I knew I had to leave the show, that’s when I knew for sure I was doing it,” Trump says. “And they hired a big, big movie star Arnold Schwarzenegger to take my place, and we know how that turned out. Ratings went right down the tubes, it’s been a total disaster, and Mark will never, ever bet against Trump again. And I want to just pray for Arnold if we can, for those ratings. But we’ve had an amazing life together the last 14, 15 years. An outstanding man. Thank you for introducing me.”

But … how did Burnett “bet against” Trump if he quit the show and had to be replaced? Or are we over-thinking this?

Anyway, NBC’s Celebrity Apprentice most recently delivered 3.7 million viewers and a 1.0 rating on Monday among adults 18-49. Those numbers are, indeed, not good. Is this important to know? Well, the president thinks so. Oh, and he also talks about firing his agent.

But wait, there’s more. Schwarzenegger has rather quickly fired back on Twitter: “Hey Donald, I have an idea. Why don’t we switch jobs? Since you’re such an expert in ratings, then people can finally sleep comfortably again.”
