President Donald Trump is implementing a significant restructuring of the National Security Council (NSC) in May 2025. This overhaul includes reducing the NSC's size to less than 150 staffers, a significant decrease from the approximately 350 it previously held.
Secretary of State Marco Rubio is currently serving as acting national security advisor. The changes aim to consolidate national security authority under the State and Defense departments, potentially increasing their influence on Trump's foreign policy decisions.
The NSC, established during the Truman administration, advises the president on national security and foreign policy, coordinating efforts among government agencies. The restructuring reflects Trump's objective to align the NSC more closely with his administration's goals.
