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.

The comments highlighted rifts within the U.S. right wing and between two men who have been influential advisers to President-elect Donald J. Trump.

Trump ally Steve Bannon attacked Elon Musk and said he would “do anything” to keep the world’s richest person out of the White House in a new interview with an Italian newspaper, weeks after Bannon publicly derided Musk for his defense of a skilled visa program.
