Elon Musk Is Expected to Use Office Space in the White House Complex

Elon Musk is expected to use office space in the White House complex as he launches the so-called Department of Government Efficiency, which aims to slash government spending in the Trump administration, according to two people briefed on the plans.

The space anticipated for Mr. Musk’s use is in the Eisenhower Executive Office Building, which is adjacent to the White House. The location would allow Mr. Musk, who owns companies with billions of dollars in contracts with the federal government, to continue to have significant access to President-elect Donald J. Trump when he takes office this month.

Mr. Musk has had discussions with transition officials about what his level of access to the West Wing will be, but that was left unclear, according to two people briefed on the matter. Staff members and others who are able to come and go freely in the West Wing typically require a special pass.

Mr. Musk donated hundreds of millions to help Mr. Trump win the 2024 election and has been a regular by his side since then, often using one of the cottages available for rent on Mr. Trump’s property at Mar-a-Lago. During the transition, he has sat in on official meetings and at least one foreign call, and weighed in on staff and cabinet choices.

It was not clear whether Vivek Ramaswamy, Mr. Musk’s partner in leading the project, would also have office space in the Eisenhower building.

The Musk-Ramaswamy project is called the Department of Government Efficiency, or DOGE, but it is not a “department” in the sense of the Justice Department — an official, congressionally authorized part of the government. Mr. Musk’s status and the project have raised myriad issues about the rules for outsiders helping to wield governmental power.
