June 5 (UPI) -- President Donald Trump and former Department of Government Efficiency Director Elon Musk are slinging accusations after an apparent end to their short-lived friendship.

Trump on Thursday accused Musk of going "crazy" after the president canceled the federal electric vehicle mandate imposed by the Biden administration.

"I took away his EV mandate that forced everyone to buy electric cars that nobody else wanted," Trump said in a Truth Social post on Thursday. "He just went crazy!"

Trump also has threatened to end all government contracts with the Musk-founded Tesla and suggested that would be a fast way to reduce government spending.
