President Trump made Elon Musk, head of the Department of Government Efficiency, a 'special government employee' at the White House. Here's what that means.

The billionaire's campaign to radically upend federal agencies is stunning former White House officials, even in a political moment when many things are described as unprecedented.

After controversially being granted access to the U.S. Treasury’s payments system, Elon Musk and his nongovernmental team of government spending slashers have now gotten their hands on a federal human resources database containing sensitive data on millions of federal employees.

Musk’s team at the Department of Government Efficiency was given access to the Treasury Department’s payment system over the weekend.

Young staffers from Musk’s government-efficiency initiative gained access to sensitive information to cap a weeklong effort that puts the aid agency’s fate in question.
