The Homeland Security Council (HSC), the successor to the Office of Homeland Security, was created by Homeland Security Presidential Directive 1 (HSPD-1) on October 29, 2001. The HSC has a mission to ensure coordination of all homeland security-related activities among executive departments and agencies and promote the effective development and implementation of all homeland security policies and is led by the Assistant to the President for Homeland Security and Counterterrorism. As with the National Security Council, the Homeland Security Council has a full-time staff and is made up of the Cabinet Secretaries and White House senior officials with homeland security responsibilities. Because of its policy coordination and advisory responsibilities, the HSC interacts frequently with the Department of Homeland Security. When it established the HSC, the White House also created a new homeland security branch within the Office of Management and Budget (OMB).
