What is Elon Musk's official role at Doge (Department of Government Efficiency)?

Elon Musk serves as a special government employee at the White House, working at the direction of President Donald Trump. Despite the president introducing him as the head of Doge in multiple interviews, an affidavit from the White House Office of Administration contradicts this claim, stating that Musk is not an employee of the US Doge Service or its temporary organization. White House Press Secretary Karoline Leavitt clarified this discrepancy, confirming that Musk's official capacity is as a special government employee serving under the president's direction, rather than having a formal leadership title within the Doge structure itself.
