On President Donald Trump’s authority alone, Elon Musk, the world’s richest man, has been unleashed on federal agencies. Employees from Musk’s companies and those of his allies, as well as young staffers he’s recruited, are wresting authority from career workers and commandeering computer systems.

While some have been public about their involvement, others have attempted to keep their roles secret, scrubbing LinkedIn pages and other sources of data. With little information from the White House, ProPublica is attempting to document who is involved and what they are doing.

Musk’s team, known as the Department of Government Efficiency, has already thrown entire swaths of the federal government and its programs into disarray — programs that serve millions of Americans.

Musk himself has made no secret of his intentions, saying that DOGE is a “wood chipper for bureaucracy” and that he is “deleting” agencies.

A White House spokesperson wrote, “Those leading this mission with Elon Musk are doing so in full compliance with federal law, appropriate security clearances, and as employees of the relevant agencies, not as outside advisors or entities.” None of the people identified responded to requests for comment.
