White House deputy national security adviser Andy Baker will leave the Trump administration in the coming weeks, marking the latest change to a national security team that has undergone a shake-up in recent months.

National security officials in Washington widely view Baker, who also served as a national security adviser to Vice President JD Vance, as a low-key but influential figure inside the White House.

A former State Department official, academic and Vance adviser when the vice president was in the Senate, Baker had historically advocated for a more restrained American foreign policy that questioned the wisdom of long-term foreign conflicts.

He was also among the figures who helped craft Vance’s speech to the Munich Security Conference last year, during which the vice president warned European leaders that alleged censorship and democratic backsliding posed risks as severe to the continent as external threats, like those posed by China and Russia.

“I’m proud of everything we’ve achieved and, of course, am incredibly grateful to the President, Vice President and Secretary Rubio,” Baker wrote in a statement provided to Reuters. “I’ll never be far away.”

In separate statements, Vance and Secretary of State Marco Rubio praised the outgoing deputy national security adviser, whose departure was first reported by Axios.

Staff changes

Baker, who has a young family, stayed on at the White House months longer than originally planned to help with some key staff transitions, according to a person close to him.

Mike Needham, a high-ranking State Department official close to Rubio, joined the White House in late May as another deputy national security adviser alongside Baker, the person noted.

Cliff Sims, a White House and intelligence official during Trump’s first term, succeeded Baker as national security adviser to Vance at around the same time.

There have been additional staff departures at lower levels of the White House’s national security team in recent months. The top officials on the National Security Council overseeing Europe and Latin America both departed in June.

The broader significance of the turnover is unclear. While Baker was present at some high-level talks and was considered far more influential than some of his peers, the Trump administration has often dealt with its biggest foreign policy challenges at the principal level, delegating relatively little responsibility even to its highest-level staff.

Outside the national security space, the White House has in recent days announced the impending departure of White House Press Secretary Karoline Leavitt and White House Counsel David Warrington.
