A White House official declared that Mr. Musk was not the administrator of the so-called Department of Government Efficiency. So who is?

Elon Musk, the incredibly wealthy man who is making drastic cuts to the federal government, is actually not in charge of the Trump-created Department of Government Efficiency, according to a Trump administration personnel official.

The Trump administration has increasingly downplayed billionaire Elon Musk’s level of authority in recent days, repeatedly claiming in legal filings he can’t unilaterally make decisions and doesn’t formally run the Department of Government Efficiency he was tapped to lead—even as reports and the billionaire’s own comments indicate Musk has been behind broad cuts throughout the federal government.
