Judith Exner (January 11, 1934 – September 24, 1999) was an American woman who claimed to be the mistress of U.S. president John F. Kennedy and Mafia leaders Sam Giancana and John Roselli. She was also known as Judith Campbell Exner, and Judith Campbell. Early life She was born Judith Eileen Katherine Immoor in Fort Lee, New Jersey; Her parents were Frederick Immoor, an architect of German descent, and Katherine (née Shea), who was of Irish descent. When she was a child, her family moved to the Los Angeles area, where she grew up in Pacific Palisades. After her mother nearly died in an auto accident, Judith withdrew from school at the age of 14 and was tutored at home. Her older sister Jacqueline later became an actress and took the professional name Susan Morrow. Marriage and family In 1952, at the age of 18, Judith married actor William Campbell; they divorced in 1958. She claimed to have had an 18-month relationship with then-Senator John F. Kennedy, beginning in 1960, which continued after he was elected President of the United States. She had a son, David Bohrer, from a later relationship. In 1975, Campbell married again, to Dan Exner, a golfer. They separated in 1988. John F. Kennedy According to Michael O'Brien of the Washington Monthly, on February 7, 1960, Frank Sinatra and Campbell were in Las Vegas, where Sinatra introduced her to John F. Kennedy, then a senator from Massachusetts and presidential candidate. In her 1977 memoir, she said that she became one of JFK's mistresses for a period of about two years, frequently visiting him in the White House after he was elected president. Her account was supported by phone records and other documentation, although Kennedy staff and supporters attacked her veracity when she published her memoir. A few months later in 1960, Sinatra introduced Campbell to "Sam Flood," who was actually Sam Giancana, the leading figure in the Chicago Mafia. She also became involved with him and knew his associate John Roselli. Church Committee Exner received national media attention when she testified in 1975 before the Church Committee investigating CIA assassination attempts on Fidel Castro. Roselli testified to the committee about Mafia involvement in the CIA attempt on Castro's life. When the Church Committee report was released in December 1975, it said that a "close friend" of President Kennedy had also been a close friend of mobsters
