Cathleen Ann O’Brien (born 4 December 1957, Muskegon, Michigan) is an American who claims to be a victim of Project MKULTRA, a program funded by the Central Intelligence Agency to research the use of drugs for intelligence purposes. O’Brien made these claims in Trance Formation of America (1995) and Access Denied: For Reasons of National Security (2004) which she co-authored with her husband Mark Phillips. O’Brien is one of many people publicly claiming to have survived ‘CIA mind control’ programs.
There is no credible evidence for O’Brien’s memories, which were retrieved through the use of hypnosis. The specific program which she claimed was responsible for her dissociative identity disorder, Project Monarch, is not mentioned in reviews of MKULTRA, its alleged parent program. Because most MKULTRA records were deliberately destroyed in 1973 by order of then CIA Director Richard Helms, it has been difficult, if not impossible, for investigators to gain a complete understanding of the more than 150 individually funded research sub-projects sponsored by MKULTRA and related CIA programs. She also claims recollection of child abuse – to her and her daughter – by international pedophile rings, drug barons and satanists, as part of a sex slave aspect to her ‘trauma based mind control programming’. Individuals; from United States, Canadian, Mexican and Saudi Arabian government officials, to stars of the Country and Western music scene; are among those she accuses of these crimes. Investigations into the story produced no credible evidence and numerous inconsistencies.
