John Roselli and Sam Giancana." Campbell's identity as the close friend was leaked to The Washington Post, which publicized it. William Safire in The New York Times also published it. The Committee had sent Exner a subpoena to make her testify. By then, married to Dan Exner, Judith Exner called a press conference that month and denied any knowledge of Mafia involvement with Kennedy. Memoir In 1977, Exner published Judith Exner: My Story. In her memoir, she said that her relationship with Kennedy was entirely personal. She also said that Frank Sinatra later introduced her to Sam Giancana, with whom she also became intimate. She said that Giancana never asked her for any information related to Kennedy. She also said that John Roselli was her friend. Aside from her own alleged affair with JFK, Exner claimed to have knowledge of other women who had affairs with Kennedy.
