Tesla CEO Elon Musk, a former adviser to President Donald Trump who is now engaged in a feud with the White House, accused top MAGA ally Steve Bannon on Tuesday of being connected to the notorious convicted sex offender Jeffrey Epstein.

Bannon, an ideological hard-liner on matters such as immigration, has for years attacked Musk, whose more pragmatic approach to various policies has outraged him. While Bannon, who served as a top aide to Trump during his first term, has conceded that Musk did a “brilliant” job leading the bureaucracy-slashing Department of Government Efficiency this year, he went for the jugular after the Tesla CEO had a public falling out with the White House over the president’s prized “big, beautiful,” tax cut bill.
