MKULTRA
In 1974, the journalist Seymour Hersh exposed the CIA's illegal spying on U.S. citizens and how the CIA had conducted non-consensual drug experiments. His report started the lengthy process of bringing long-suppressed details about MKUltra to light. Project MKUltra came to light in the spring of 1977 during a wide-ranging survey of the CIA's Technical Services Division. John K. Vance, a member of the CIA inspector general's staff, discovered that the agency was running a research project that included administering LSD and other drugs to unwilling human subjects.
