Jefferies used explicit terms after the British TV personality took issue with Trump’s restrictive executive order being called “a Muslim ban.” That’s despite it prohibiting people from seven Muslim-majority countries from entering the U.S.

Morgan accused Jefferies of whipping up hysteria. But Jefferies didn’t let up.

“This is what you do, Piers. You say, ‘He hasn’t done this, he hasn’t done that, he’s not going to do all these things,’” the comedian said.

“Give him a fucking chance, mate. Hitler didn’t kill the Jews on the first day, he worked up to it, mate.”

When Morgan labeled his verbal attack as “ridiculous,” Jefferies responded by flipping him off.

“You just like that you won ‘The Apprentice’ and you have a famous friend, mate. That’s all you fucking like,” he added.
