COINTELPRO was a series of covert and illegal projects conducted by the United States Federal Bureau of Investigation aimed at surveilling, infiltrating, discrediting, and disrupting domestic American political organizations. FBI records show COINTELPRO resources targeted groups and individuals the FBI deemed subversive, including feminist organizations, the Communist Party USA, anti–Vietnam War organizers, activists of the civil rights movement and Black Power movement, environmentalist and animal rights organizations, the American Indian Movement, independence movements, a variety of organizations that were part of the broader New Left, and unrelated groups such as the Ku Klux Klan.
The FBI has used covert operations against domestic political groups since its inception; however, covert operations under the official COINTELPRO label took place between 1956 and 1971. COINTELPRO tactics are still used to this day and have been alleged to include discrediting targets through psychological warfare; smearing individuals and groups using forged documents and by planting false reports in the media; harassment; wrongful imprisonment; and illegal violence, including assassination. According to a Senate report, the FBI's motivation was "protecting national security, preventing violence, and maintaining the existing social and political order".
FBI Director J. Edgar Hoover issued directives governing COINTELPRO, ordering FBI agents to "expose, disrupt, misdirect, discredit, or otherwise neutralize" the activities of these movements and especially their leaders. Under Hoover, the agent in charge of COINTELPRO was William C. Sullivan. Attorney General Robert F. Kennedy personally authorized some of the programs, giving written approval for limited wiretapping of Martin Luther King's phones "on a trial basis, for a month or so." Hoover extended the clearance so his men were "unshackled" to look for evidence in any areas of King's life they deemed worthy.
