The President's Intelligence Advisory Board (PIAB), with its component Intelligence Oversight Board (IOB), is an independent element within the Executive Office of the President. The President’s Intelligence Advisory Board exists exclusively to assist the President by providing the President with an independent source of advice on the effectiveness with which the Intelligence Community is meeting the nation’s intelligence needs, and the vigor and insight with which the community plans for the future. The Board has access to all information needed to perform its functions and has direct access to the President. The Intelligence Oversight Board oversees the Intelligence Community’s compliance with the Constitution and all applicable laws, Executive Orders, and Presidential Directives. It complements and supplements, rather than duplicates the oversight roles of the Director of National Intelligence, Department and Agency Inspectors General and General Counsels, and the Congressional Oversight Committees. For more than five decades the PIAB has acted as a nonpartisan body, offering the President objective, expert advice on the conduct of U.S. intelligence.
