WASHINGTON – President Donald Trump threatened to end billions of dollars of federal contracts with Elon Musk's companies on June 5 after the alliance between Trump and the world's richest man blew up in spectacular fashion.

Trump brought up Musk's federal contracts in a post on Truth Social after the two men hurled personal attacks as Musk, a former top Trump advisor, tries to build momentum to defeat the president's tax and policy bill.

"The easiest way to save money in our Budget, Billions and Billions of Dollars, is to terminate Elon’s Governmental Subsidies and Contracts," Trump said in a post on his social media platform. "I was always surprised that Biden didn’t do it!"

In a separate post, Trump said he asked Musk to stop working at the White House. The Tesla and SpaceX CEO spent the past four months leading the administration's Department of Government Efficiency (DOGE), which set out to slash government bloat and eliminate waste, fraud and abuse.

"Elon was 'wearing thin,'" Trump said. "I asked him to leave, I took away his EV Mandate that forced everyone to buy Electric Cars that nobody else wanted (that he knew for months I was going to do!), and he just went CRAZY!"
