An investigative reporter told Congress this week he discovered documents linking the Charles Manson murders to clandestine CIA mind-control experiments, reviving decades-old questions about the agency's notorious MKUltra program during a House hearing on declassifying federal secrets.
The House Oversight Committee's Task Force on the Declassification of Federal Secrets heard testimony from investigative journalist Tom O'Neill and historian Stephen Kinzer as Republicans pressed for the release of newly discovered CIA records tied to MKUltra, the Cold War-era mind-control program that subjected unwitting Americans to drug experiments and other clandestine research.
Task Force Chair Anna Paulina Luna, R-Fla., said the American people deserve a full accounting of the program, accusing the CIA of illegally experimenting on U.S. citizens before destroying evidence to conceal its activities.
She also revealed the agency is declassifying newly discovered MKUltra documents involving a forgery program.
O'Neill, author of "Chaos: Charles Manson, the CIA, and the Secret History of the Sixties," testified he uncovered correspondence between CIA chemist Sidney Gottlieb and psychiatrist Dr. Louis "Jolly" West after reviewing hundreds of boxes of West's papers.
According to O'Neill, the documents describe proposals involving LSD, hypnosis, memory manipulation, and behavioral modification.
He testified that West later operated near a San Francisco clinic where Charles Manson and members of his group received free medical treatment in 1967, shortly before Manson emerged as the leader of the cult responsible for the Tate-LaBianca murders.
Still, O'Neill stopped short of claiming he had proven Manson was an intelligence asset.
When Luna asked whether Manson had been connected to MKUltra, O'Neill replied the theory remains unproven, although he argued federal authorities repeatedly allowed Manson to violate parole, avoid prosecution, and continue building his cult while under government supervision.
He also suggested psychiatrist West's involvement with Jack Ruby, Lee Harvey Oswald's killer, kept Ruby from publicly telling his story.
Those allegations have not been confirmed by official government investigations.
Kinzer, author of "Poisoner in Chief," described MKUltra as one of the CIA's darkest chapters, alleging it involved prisoners, psychiatric patients, and unwitting civilians subjected to LSD, hypnosis, and psychological experimentation.
He testified that CIA Director Richard Helms ordered most MKUltra records destroyed in 1973, leaving only scattered documents that later surfaced through Freedom of Information Act requests.
The hearing also examined allegations that people may have died during overseas MKUltra experiments and that additional records could shed light on unresolved questions, although historian David Barrett cautioned against expecting a "smoking gun" from the newly discovered files.
Luna pledged the task force will continue pressing the CIA to release additional records, saying lawmakers intend to determine the full scope of the program and ensure the American people have the complete record.
