Billionaire Elon Musk alleged that President Trump has ties to convicted sex offender and financier Jeffrey Epstein as the part of his growing feud with the president, a fight that boiled over and turned personal on Thursday.

“Time to drop the really big bomb,” Musk wrote on X, the social platform he owns. “[Trump] is in the Epstein files. That is the real reason they have not been made public.”

Minutes later, he followed up: “Mark this post for the future. The truth will come out.”

A source familiar emphasized to The Hill that Trump kicked Jeffrey Epstein out of his Palm Beach Golf Club years ago and noted the administration previously released Epstein files with the President’s name included.

Musk for months, before and after the campaign, spoke glowingly of Trump’s character, the source emphasized, noting at one point the billionaire posted on social media saying he “loves him as much as a straight man can love a straight man.”

Musk’s allegation came just minutes after Trump threatened to cancel government contracts with Musk’s companies, calling him “crazy” and escalating an explosive feud between the two former allies.

The billionaire tech and media mogul suggested earlier Thursday that Trump would not have gotten elected last fall without him and called him ungrateful.
