The chaotic blitz by Elon Musk’s Department of Government Efficiency has triggered legal objections across Washington, with officials in at least a half-dozen federal agencies and departments raising alarms about whether the billionaire’s assault on government is breaking the law.

Over the past two weeks, Musk’s team has moved to dismantle some U.S. agencies, push out hundreds of thousands of civil servants and gain access to some of the federal government’s most sensitive payment systems. Musk has said these changes are necessary to overhaul what he’s characterized as a sclerotic federal bureaucracy and to stop payments that he says are bankrupting the country and driving inflation.

But many of these moves appear to violate federal law, according to more than two dozen current and former officials, one audio recording, and several internal messages obtained by The Washington Post. Internal legal objections have been raised at the Treasury Department, the Education Department, the U.S. Agency for International Development, the General Services Administration, the Office of Personnel Management, the Equal Employment Opportunity Commission and the White House budget office, among others.
