Steve Bannon is ramping up his attack on Elon Musk. And this time he’s threatening violence. The House of MAGA has been up in flames this week over Musk’s plan to protect immigrants with H1-B visas, while diehard conservatives like the president-elect’s former strategist Bannon and Trump loyalist Laura Loomer have said foreign workers should be deported and replaced with “real” Americans.

I mean, it was embarrassing,” Steve Bannon said on Monday, referencing Elon Musk’s tweets over the weekend when he said the H-1B visa program needed to be “reformed.”

Donald Trump has backed Elon Musk in supporting visas for skilled migrants. The president-elect waded into a row that has split the Republican party by defending H1B visas, which permit highly-educated foreigners to work in the US for up to six years.
