WATCH: Arnold Schwarzenegger offers Donald Trump job swap

Arnold Schwarzenegger has challenged Donald Trump to a job swap, offering to “take over” as US President.

The ‘Terminator’ actor hit back at the commander-in-chief’s comments on Thursday after he urged people to “pray for Arnold” and pointed out that the US version of ‘Celebrity Apprentice’ has suffered a slump in ratings since the former Governor of California took over in the boardroom from Trump.

Trump branded the new series of ‘Celebrity Apprentice’ a “disaster” during the National Prayer Breakfast in Washington, DC.

He said: “We had tremendous success on ‘The Apprentice’, and when I ran for president, I had to leave the show… 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 [executive producer] Mark [Burnett] will never, ever bet against Trump again. And I want to just pray for Arnold, if we can, for those ratings, OK?”

In response, the 69-year-old actor quickly shared a video online and suggested he and the president “switch jobs”.

He said: “Hey Donald, I have a great idea: 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.”

Arnold – who was Governor of California for eight years until 2011 – previously admitted he would have campaigned to be the Republican candidate for presidency this year if he’d been eligible to run for the position.

The Austrian actor said: “If I’d been born in America, I would’ve run.

“Because now? This was a very good time to get in the race.”
