In December 1974, the New York Times reported that the CIA had conducted illegal domestic activities, including experiments on U.S. citizens during the 1960s. That report prompted investigations by both Congress (in the form of the Church Committee) and a presidential commission (known as the Rockefeller Commission) into the domestic activities of the CIA, the FBI, and intelligence-related agencies of the military. Congressional hearings and the Rockefeller Commission report revealed to the public for the first time that the CIA and the DOD had conducted experiments on both cognizant and unwitting human subjects as part of an extensive program to influence and control human behavior through the use of psychoactive drugs (such as LSD and mescaline) and other chemical, biological, and psychological means. They also revealed that at least one subject had died after administration of LSD. Frank Olson, an Army scientist, was given LSD without his knowledge or consent in 1953 as part of a CIA experiment and apparently committed suicide a week later. Subsequent reports would show that another person ... died as a result of a secret Army experiment involving mescaline. The CIA program, known principally by the codename MKULTRA, began in 1950 and was motivated largely in response to alleged Soviet, Chinese, and North Korean uses of mind-control techniques on U.S. prisoners of war in Korea. Most of the MKULTRA records were deliberately destroyed in 1973 by order of then-Director of Central Intelligence Richard Helms.
