The leading role the former “first buddy” took in stoking the Epstein controversy shows how he remains a potent political risk for Trump months after he publicly left the White House.

Elon Musk has weighed back into the Donald Trump and Jeffrey Epstein drama he helped create with a string of spicy social media posts. On Thursday, the president was pulled back into the Epstein saga after a Wall Street Journal article claimed Trump once sent the sex offender a letter including a drawing of a naked woman.

The series of posts signals a growing rift between two of the most high-profile figures on the political and tech stage — with Epstein transparency at the center of the tension. Trump previously indicated he would target Elon Musk’s companies after the Tesla CEO announced that Trump was in the Epstein files.
