Cathy O'Brien (conspiracy theorist)

Cathy O'Brien (born December 4, 1957) is an American conspiracy theorist and author who claims to have been a victim of a government mind control program called "Project Monarch", which she alleges was part of the CIA's Project MKUltra. O'Brien made these assertions in Trance Formation of America (1995) and Access Denied: For Reasons of National Security (2004), both of which she co-authored and self-published with her husband, Mark Phillips. According to scholars, there is no credible evidence for O'Brien's claims and there are numerous inconsistencies in her story.
