1977 - United States Senate Hearing on MKULTRA.

From wikipedia:

Project MK-ULTRA, or MKULTRA, was the code name for a covert CIA mind-control and chemical interrogation research program, run by the Office of Scientific Intelligence, that began in the early 1950s and continued at least through the late 1960s. There is much published evidence that the project involved the surreptitious use of many types of drugs, as well as other methodology, to manipulate individual mental states and to alter brain function.

Project MK-ULTRA was first brought to wide public attention in 1975 by the U.S. Congress, through investigations by the Church Committee, and by a presidential commission known as the Rockefeller Commission. Investigative efforts were hampered by the fact that CIA Director Richard Helms ordered all MK-ULTRA files destroyed in 1973; the Church Committee and Rockefeller Commission investigations relied on the sworn testimony of direct participants and on the relatively small number of documents that survived Helms’ destruction order.

After Leo Ryan was murdered at Jonestown, his children filed a lawsuit claiming that the CIA had been operating Jonestown as part of their MK-ULTRA program, and that Richard Dwyer, the Deputy Chief of Mission from the US Embassy who had organized the trip on Ryan’s behalf, was a CIA agent. The lawsuit was dismissed for reasons that have never been made public, and the majority of U.S. government records concerning Jonestown remain sealed to this day.
