Established by the National Security Act of 1947, the National Security Council (NSC) has evolved over the years from a statutorily mandated meeting of cabinet-level officials into a complex system of coordination, adjudication, and policy formulation executed
by a large professional staff. This expansion of authority has allowed the NSC to set strategy across a wide spectrum of domestic and international issues. Yet the appointment of the head of the organization, the National Security Advisor, does not require
the advice and consent of the Senate.
