White House deputy national security adviser Andy Baker is departing the Trump administration in the coming weeks, the second high-profile exit this week and the latest in a string of National Security Council shake-ups.
Baker, a former State Department Foreign Service officer who has served alongside Vice President JD Vance for more than three years, will move to the private sector and join America Global Strategies, the consulting firm co-founded by Robert O'Brien, who served as Trump's national security adviser during his first term. The Hill reported Baker's planned departure on Friday, one day after Axios broke the news.
No official reason was given for the move, though the Washington Examiner reported Baker cited a desire to spend more time with his family. By multiple accounts, he stayed on months longer than he originally planned, specifically to help his successors settle in.
Baker kept a relatively low profile for someone with his portfolio. He joined Vance's Senate office in 2023 as a national security adviser, then followed Vance into the White House. Along the way, he pushed for a more restrained approach to American foreign policy and questioned prolonged U.S. involvement in conflicts overseas, positions that aligned with the administration's broader "America First" posture.
His fingerprints were on some of the administration's most consequential national security work. Politico, as cited by The Hill, reported that Baker played a major role in crafting the administration's National Security Strategy. He was also part of the U.S. delegation that conducted the first face-to-face talks with Iran in Pakistan earlier this year, a diplomatic channel that produced a 60-day ceasefire framework before it ultimately collapsed, the Washington Times reported.
The praise from senior officials was unanimous and specific. Vice President Vance called Baker an "exceptionally gifted, deeply thoughtful" adviser and issued a fuller statement:
"He has been an indispensable member of our administration's national security team. For the over three years that Andy has been by my side, I've always valued his counsel and have been grateful for the difficult work he's done."
Secretary of State Marco Rubio said Baker had been "an invaluable asset and key member of the President's national security team who has greatly advanced the America First agenda." Steve Witkoff, as quoted by the Washington Examiner, added that "from day one, Andy has worked tirelessly to put America first and get deals done for the President around the world."
Mike Needham, who joined the White House in May as a deputy national security adviser and is a longtime Rubio ally, described Baker as "a brilliant foreign policy mind and close friend." Baker, for his part, kept his own farewell brief.
"This has been an amazing journey. I'm proud of everything we've achieved and, of course, am incredibly grateful to the President, Vice President, and Secretary Rubio. I'll never be far away."
Baker's exit is not happening in isolation. It follows Press Secretary Karoline Leavitt's announced resignation earlier the same week, making it the second high-profile White House departure in a matter of days. The pattern extends further back: top NSC officials overseeing Europe and Latin America left in June.
The broader context is a deliberate restructuring. Trump slashed half of the NSC staff last year as part of an effort to streamline the council. In May 2025, after the departure of national security adviser Mike Waltz, the president named Rubio to fill that role while continuing to serve as secretary of State, an unusual dual portfolio that gives Rubio direct leadership over the NSC. High-profile departures from government are nothing new in Washington; Justice Alito recently ended weeks of retirement speculation by confirming he would stay on the Supreme Court, a reminder that not every rumored exit becomes a reality.
Cliff Sims replaced Baker as Vance's national security adviser earlier this summer and will remain in that role. Needham stays on as deputy national security adviser. Baker stayed longer than planned specifically to help both men transition into their positions, a detail that suggests an orderly handoff rather than a sudden rupture.
Still, the steady stream of exits raises a practical question: whether the NSC, already halved in size, can absorb the loss of institutional knowledge that walks out the door with experienced hands like Baker. The administration has not publicly addressed that concern. The departures also come at a moment when the Iran ceasefire framework Baker helped negotiate has collapsed, leaving a live foreign-policy challenge without one of its principal architects in the room.
Former national security adviser John Bolton's own post-government trajectory took a very different turn, but Baker's next chapter looks more conventional: a move to O'Brien's consulting firm, where his foreign-policy experience and administration contacts will have obvious commercial value.
Washington has no shortage of speculation about who might leave next, and the revolving door at the NSC will keep feeding that appetite. But the people who actually worked with Baker are telling a consistent story: he did his job, stayed longer than he had to, and left on good terms.
That is how government service is supposed to work. The question now is whether the team he left behind can keep the policy machinery running at the same level, with half the staff and one fewer "brilliant foreign policy mind" in the building.
