Don Lemon unleashed a string of expletives at supporters of U.S. President-elect Donald Trump following a split in the Republican Party over skilled immigrants.

Last Friday, the former CNN host trashed Trump’s supporters by calling them “dumb f—ing idiots” who have “stupid MAGA brain.”

“Oh my gosh, I love this,” Lemon said while laughing out loud during an episode of The Don Lemon Show.

“Now you’re finding out you dumb f—ing idiots. Now you’re just figuring this s— out. You’re so f—ing stupid and you deserve it. You f—ing deserve it because you’re so dumb. Yes I am gloating over your stupidity.

“You have been co-opted because you’re in a f—ing cult and you don’t even realize it because you have stupid MAGA brain and you don’t get it. How stupid and dumb are you?”

Lemon was commenting on the Republican infighting over H-1B visas, which allows U.S. companies to employ foreign workers in specialty occupations that cannot be filled by American workers, especially in the tech sector.

Visa holders are allowed to stay for three years and can be extended to six years before they would be required to reapply.

Last week, billionaire entrepreneurs Elon Musk and Vivek Ramaswamy — co-chairs of the Department of Government Efficiency (DOGE) — shared their support for H-1B visas.

“The reason I’m in America along with so many critical people who built SpaceX, Tesla, and hundreds of other companies that made America strong is because of H-1B,” Musk said in response to a critic on social media site X, adding he “will go to war on this issue the likes of which you cannot possibly comprehend.”

However, other Republicans like former Trump adviser Steve Bannon have been critical of the visa program, calling it a “scam” that “takes American jobs and brings over what essentially become indentured servants at lower wages.”

Over the weekend, Trump said that he supports immigration visas for highly skilled workers.

“I’ve always liked the visas, I have always been in favour of the visas. That’s why we have them,” Trump told the New York Post on Saturday.

“I have many H-1B visas on my properties. I’ve been a believer in H-1B. I have used it many times. It’s a great program,” Trump added.

The immigration policy flareup came after Sriram Krishnan, a 39-year-old Indian-American venture capitalist and podcaster, was named a senior adviser on artificial intelligence by Trump.

“So Krishnan’s appointment triggered an anti-Indian backlash on social media, particularly given his past advocacy for increasing green card and immigration broadly,” Lemon said.

“Oh no, immigration,” he continued in a mocking tone. “We can’t do the immigration because, you know, the immigration, it triggers some people. You know what they’re saying about the anti-immigration stuff, right? Who’s it to say that one of the jobs you might be seeking won’t be one of those white jobs?”
