The various departments and agencies that constitute the U.S. intelligence community (IC) cooperate to fulfill the goals of Executive Order 12333. Members of the IC are federal-government agencies, services, bureaus, and other organizations within the executive branch that play a role in the business of national intelligence. Some have responsibilities concerned solely with intelligence; others are concerned primarily with missions other than intelligence but do have intelligence responsibilities. In these cases, only that part of the organization with intelligence responsibilities is considered to be a part of the IC (Keegan, 2008).
