Organizational History
The U.S. Commission on CIA Activities within the United States was an ad hoc commission, created by President Gerald R. Ford via Executive Order 11828 on 4 January 1975, and known as the Rockefeller Commission after its chair, Vice President Nelson A. Rockefeller. The commission was charged with determining whether the Central Intelligence Agency (CIA) conducted domestic surveillance and other activities. Its final report, published June 6, 1975, found that the CIA had conducted unlawful acts within the United States that included infiltrating dissident groups, opening private mail, testing behavior-inducing drugs on unknowing citizens, and subjecting foreign defectors to physical abuse and prolonged confinement.
