The Rockefeller Commission reported in June 1975 that the CIA had given LSD to people who did not know they were being tested, that this was “clearly illegal”, and that one person died. [1] That was the first official public account. MKULTRA’s name itself became public during the investigations of 1975. [4]

The Church Committee’s final report in April 1976 covered MKULTRA, MKDELTA, MKNAOMI, the Olson case and the failure of oversight. [2] Its earlier report on assassination plots described the poison prepared for Lumumba. [3]

The joint Senate hearing on 3 August 1977 took testimony from Turner, Gittinger and others about the newly found records. [4]
