Musk and Trump traded scathing missives on social media in early June. Trump has previously threatened to end government contracts with Musk's companies, saying during their June fallout that "the easiest way to save money" would be to "terminate Elon’s Governmental Subsidies and Contracts."

Elon Musk warned that he would boost primary challenges against Republican lawmakers who vote for President Trump's so-called "big, beautiful bill."

While President Trump is banking on his "Big, Beautiful Bill," members of the Republican Party remain conflicted over key aspects of the massive piece of legislation.
