Arnold Schwarzenegger’s time as host of NBC’s “The Celebrity Apprentice” will be a short one.

The actor — who spent some of his time as host jousting with President Trump — has informed NBC that he will not return. He confirmed the news in a statement.

“I loved every second of working with NBC and Mark Burnett,” Mr. Schwarzenegger said, referring to the creator of “The Apprentice,” the show that turned Mr. Trump into a reality-TV star. “Everyone — from the celebrities to the crew to the marketing department — was a straight 10, and I would absolutely work with all of them again on a show that doesn’t have this baggage.”

President Trump, responding on Saturday morning to Mr. Schwarzenegger’s decision, could not resist the temptation once again to take a shot at his successor on the show and discuss its ratings.

After a series of tweets in which he accused — without evidence — former President Obama of tapping his phone, Mr. Trump then claimed that Mr. Schwarzenegger was not “voluntarily leaving the Apprentice, he was fired by his bad (pathetic) ratings.”
