The U.S. Office of Personnel Management emails were sent to federal workers on Saturday, shortly after Musk wrote in a post on X that “all federal employees will shortly receive an email requesting to understand what they got done last week. Failure to respond will be taken as a resignation.”

Musk is "an employee of the White House Office" and "holds a position as a non-career Special Government Employee," the filing said. "Like other senior White House advisors, Mr Musk has no actual or formal authority to make government decisions himself."
