Musk attacked Trump directly over his signature spending bill for the first time Thursday, sparking an explosive back-and-forth.

An intense public feud erupted on Thursday between President Donald Trump and his one-time ally, billionaire Elon Musk, with an argument about Trump’s massive tax and domestic policy bill raging across social media and in the Oval Office.

The fallout between Elon Musk and Donald Trump began after the former denounced the President's ‘big, beautiful’ spending bill.
