The breakup between the president of the United States and the world’s richest man is unfurling much like their relationship started — rapidly, intensely and very publicly. As President Donald Trump sat in the Oval Office on Thursday with Germany's leader at his side, he lamented his soured relationship with Elon Musk, his adviser-turned-social media antagonist. Trump said he was “very disappointed” with Musk after the billionaire former backer lambasted the president’s signature bill of tax cuts and spending plans.

Days after leaving the White House, Elon Musk slammed President Trump's big tax bill. "I’m sorry, but I just can’t stand it anymore," Musk said.

Donald Trump is fuming at Elon Musk for the ex-DOGE leader's comments about the president's 'disgusting' spending bill.
