Arnold Schwarzenegger has urged Donald Trump to go back to reality TV so "people can finally sleep comfortably again".
The Terminator star and former Republican governor of California hit back after President Trump mocked his replacement as the host of The Celebrity Apprentice in the US.
The president suggested the show had been a "total disaster" since Schwarzenegger took over.
The actor responded in a video clip, saying: "Hey Donald, I have a great idea - why don't we switch jobs?
"You take over TV, because you're such an expert in ratings, and I take over your job, and then people can finally sleep comfortably again, hmm?"
Austrian immigrant Schwarzenegger, who has previously said President Trump's ban on refugees "makes us look stupid", is the latest Hollywood name to lock horns with the new president.
