Final answer:
The Mayor of New York City is not a member of the National Security Council. The NSC includes members such as the President, Vice President, Secretaries of State, Defense, and Homeland Security, National Security Advisor, among others.
Step-by-step explanation:
The Mayor of New York City is not a member of the National Security Council (NSC). The NSC is a principal forum used by the President of the United States for considering national security and foreign policy matters with senior national security advisors and Cabinet officials. Its members include the President, the Vice President, the Secretary of State, the Secretary of Defense, the Secretary of Homeland Security, and the President's National Security Advisor. Additionally, the Chairman of the Joint Chiefs of Staff serves as the military advisor to the Council, and the Director of National Intelligence serves as the intelligence advisor.
The NSC's goal is to advise and assist the President on national security and foreign policies, and to coordinate these policies among various government agencies. The Mayor of New York City, while potentially involved in discussions regarding security at the municipal level, does not have a role within this federal body.
