WASHINGTON ― President Donald Trump on Thursday broke his silence on Elon Musk following the former White House adviser’s harsh criticism of Trump’s signature legislation on Capitol Hill. And things got ugly fast.

Within hours, the two onetime allies were trading insults on social media, with Trump eventually threatening to cancel government contracts for Musk’s various companies.

“The easiest way to save money in our Budget, Billions and Billions of Dollars, is to terminate Elon’s Governmental Subsidies and Contracts,” Trump wrote on Truth Social. “I was always surprised that Biden didn’t do it!”

Musk responded immediately: “Such an obvious lie. So sad.” A few minutes later, he said Trump’s name is in the FBI files related to serial sex trafficker Jeffrey Epstein.

“That is the real reason they have not been made public,” Musk wrote.
