WASHINGTON — Deputy White House National Security Adviser Andy Baker is leaving the administration in the coming weeks, concluding an 18-month tenure that placed him at the center of the administration's recalibrated foreign policy and direct talks with Iran.

A statement from Baker's office confirmed the departure, citing a personal decision to spend more time with his family. A source familiar with the matter indicated Baker had extended his service beyond his initial commitment to ensure a smooth handover of responsibilities. His portfolio, which included serving as the national security advisor to Vice President Vance, will be absorbed by Cliff Sims and Mike Needham within the existing structure, requiring no new taxpayer-funded hiring process.

Baker's exit marks a loss of institutional memory amid ongoing sensitive negotiations. He was personally involved in direct engagements with Iran this year, a diplomatic track pursued as an alternative to the entanglements of perpetual Middle Eastern conflict. The continuity of those negotiations now shifts to other aides as Baker plans to join the private-sector firm of Robert O'Brien, who served as National Security Advisor during a previous administration.

“Andy is an exceptionally gifted, deeply thoughtful advisor who has served the President and me with distinction. He has been an indispensable member of our administration's national security team,” Vice President Vance said in a statement.

Secretary of State Marco Rubio, who holds the concurrent title of White House National Security Advisor, praised Baker as a key asset in advancing the administration's America First agenda. The move comes as the administration seeks to cement its doctrine of prioritizing American sovereignty against the inertia of the foreign policy establishment, a goal Baker reportedly championed internally to steer resources away from foreign lobbying interests that run counter to domestic priorities.
