National Security Advisor (United States)

The Assistant to the President for National Security Affairs (APNSA), commonly referred to as the National Security Advisor (NSA), is a senior aide in the Executive Office of the President, based at the West Wing of the White House. The national security advisor serves as the principal advisor to the President of the United States on all national security issues. The national security advisor participates in meetings of the National Security Council (NSC) and usually chairs meetings of the Principals Committee of the NSC with the Secretary of State and Secretary of Defense. The NSA also sits on the Homeland Security Council (HSC). The national security advisor is supported by NSC staff who produce classified research and briefings for the national security advisor to review and present, either to the NSC or the president. The national security advisor is appointed by the president and does not require confirmation by the United States Senate. An appointment of a three- or four-star general to the role requires Senate confirmation to maintain that rank in the new position.
