Elon Musk's social media fight with President Trump over the budget bill this week threatens to have a larger impact.

Their escalating feud threatens critical parts of the billionaire’s business empire — and leaves Republican legislators caught in a tussle between the two.

Trump, making his first comments on Musk’s criticism of his bill during an Oval Office press conference, insinuated the Tesla CEO opposes his “One Big Beautiful Bill Act” because he is “upset” the electric vehicle tax credit was removed, adding he’s not sure he’ll remain friends with Musk and alleging Musk “knew the inner workings of the bill.”
