The United States deputy national security advisor is a member of the Executive Office of the President of the United States and the United States National Security Council, serving under the president's national security advisor.
Among other responsibilities, the deputy national security advisor often serves as Executive Secretary to the National Security Council Principals Committee, and as chairman of the National Security Council Deputies Committee. The role changes according to the organizational philosophy and staffing of each White House and there are often multiple deputies to the national security advisor charged with various areas of focus.
