Implicitly criticizing the expansive role of the NSC staff under Kissinger, the Commission recommended that only the President should have line responsibility in the White House; that staff officials should not themselves issue directives to departmental officials; that, in the future, the National Security Adviser have no other official responsibilities; that the Secretary of the Treasury be made a statutory member of the NSC and that the NSC's scope be expanded to include major international economic policy issues; and that senior officials concerned with domestic policy be invited to NSC meetings when issues with domestic implications were discussed. The NSC Principals Committee, was composed of the Secretaries of State and Defense, the DCI, the Chairman of the JCS, the Chief of Staff to the President, and the National Security Adviser, who was the chairman. Hadley made fewer public appearances but emphasized the importance of the NSC staff monitoring the implementation of NSC decisions. In May 2009 the Administration announced the integration or the staffs of the National Security Council and the Homeland Security Council into a single National Security Staff (NSS), with the goal of ending "the artificial divide between White House staff who have been dealing with national security and homeland security issues." Overview of Current NSC Functions

Largely because of the major influence in policymaking exerted by Kissinger and Brzezinski, the position of National Security Adviser has emerged as a central one. Most of the NSC staff positions in the George H. W. Bush Administration were filled with government officials. The Senate does not approve the appointment of the National Security Adviser, although it does confirm statutory NSC members. 110 - 140 , §932) Congress added the Secretary of Energy to the NSC. The Role of the National Security Adviser

The NSC was created by statute, and its membership has been designated and can be changed by statute. 2007. Commission on the Organization of the Executive Branch of the Government. Report . "NSC Reform for the Post-Cold War Era," Orbis , Summer 2000. National Security Advisers
The National Security Council (NSC) was established by statute in 1947 to create an inter-departmental body to advise the President with respect to the integration of domestic, foreign, and military policies relating to the national security so as to enable the military services and the other departments and agencies of the government to cooperate more effectively in matters involving the national security. Currently, statutory members of the Council are the President, Vice President, the Secretary of State, the Secretary of Defense, and, since 2007, the Secretary of Energy; but, at the President's request, other senior officials participate in NSC deliberations. The Chairman of the Joint Chiefs of Staff and the Director of National Intelligence are statutory advisers.
The President clearly holds final decision-making authority in the executive branch. Over the years, however, the NSC staff has emerged as a major factor in the formulation (and at times in the implementation) of national security policy. Similarly, the head of the NSC staff, the National Security Adviser, has played important, and occasionally highly public, roles in policymaking. This report traces the evolution of the NSC from its creation to the present.
The organization and influence of the NSC have varied significantly from one Administration to another, ranging from highly structured and formal systems to loose-knit teams of experts. Although it is universally acknowledged that the NSC staff should be organized to meet the particular goals and work habits of an incumbent President, the history of the NSC provides ample evidence of the advantages and disadvantages of different types of policymaking structures.
Congress enacted the statute creating the NSC and has altered the character of its membership over the years. Congress annually appropriates funds for its activities, but does not, routinely, receive testimony on substantive matters from the National Security Adviser or from NSC staff. Proposals to require Senate confirmation of the Security Adviser have been discussed but not adopted.
The post-Cold War world has posed new challenges to NSC policymaking. Some argue that the NSC should be broadened to reflect an expanding role of economic, environmental, and demographic issues in national security policymaking. The Clinton Administration created a National Economic Council tasked with cooperating closely with the NSC on international economic matters. In the wake of the 9/11 attacks, the George W. Bush Administration established a Homeland Security Council. The Obama Administration has combined the staffs of the Homeland Security Council and the National Security Council into a single National Security Staff, while retaining the two positions of National Security Adviser and Homeland Security Adviser. Although the latter has direct access to the President, the incumbent is to report organizationally to the National Security Adviser.
