The Assistant to the President for National Security Affairs, often called the National Security Advisor (NSA), is a very important helper to the President of the United States. This person works in the Executive Office of the President, located in the West Wing of the White House.

The National Security Advisor is the main person who advises the President on all issues about national security. This means they help the President make decisions to keep the country safe. The NSA also attends meetings of the National Security Council (NSC). They often lead meetings of top officials from the NSC, like the Secretary of State and Secretary of Defense, when the President is not there. The NSA is also part of the Homeland Security Council (HSC).

The President chooses the National Security Advisor. This person usually does not need to be approved by the United States Senate. However, if a three- or four-star general is chosen for the job, the Senate must approve them to keep their military rank. The current acting National Security Advisor is Marco Rubio, who started on May 1, 2025.

What the National Security Advisor Does

The job and power of the National Security Advisor can change a lot. It depends on who is in the role and how the President likes to manage things. Ideally, the National Security Advisor helps the President by giving honest advice on different ways to handle national security issues. They are not supposed to push their own ideas too much.

The National Security Advisor works directly for the President. They do not control the budgets or operations of big departments like the State Department or the Defense Department. The Secretary of State and Secretary of Defense, for example, are approved by the Senate and run their own departments. Because the National Security Advisor works so closely with the President, they can offer daily advice without being influenced by the large organizations of those departments.

During a crisis, the National Security Advisor often works from the White House Situation Room. They might also work from the Presidential Emergency Operations Center. Their job is to keep the President updated on the latest events. For example, they were very active during the September 11, 2001 events.

History of the Role

President George H. W. Bush meeting with his National Security Council about Operation Desert Shield in 1991.

The National Security Council was created in 1947, at the beginning of the Cold War. Its purpose was to help coordinate defense, foreign affairs, and intelligence. This was part of a big change that also created the Department of Defense and the Central Intelligence Agency. The law that created the NSC did not create the National Security Advisor job directly. Instead, it created an executive secretary to lead the staff. In 1949, the NSC became part of the President's main office.

Robert Cutler was the first National Security Advisor in 1953. He held the job twice during President Eisenhower's time in office. The way the system works has stayed mostly the same since then. Especially since President John Kennedy, National Security Advisors have had a lot of power and strong staff.

President Richard Nixon's National Security Advisor, Henry Kissinger, made the role even more important. He controlled what information reached the President and met with him many times a day. Kissinger also served as both National Security Advisor and Secretary of State at the same time for a while. He holds the record for serving the longest in this role, for 2,478 days. Michael Flynn holds the record for the shortest term, serving only 24 days.

Brent Scowcroft held the job for two different Presidents: President Gerald Ford and President George H. W. Bush.
