As Musk and Trump volleyed on social media, attacking each other, the former DOGE czar decided to go nuclear, shortly after the president threatened to cut government contracts with Musk’s many businesses, which have totaled $38 billion.

Still, Trump isn’t publicly chastising Musk, which is unusual. Maybe that’s because he’s waiting on a $100 million check to his political action committee, per The Wall Street Journal. Or maybe it’s because Musk is particularly close to Katie and Stephen Miller, two major Trump administration power players.
