casinos that the Mob operated in Cuba, and attempted to drive the mobsters out of the country. This made Roselli, Chicago Outfit boss Sam Giancana and Tampa boss Santo Trafficante amenable to the idea of killing Castro. According to the Family Jewels documents released in 2007, members of the American mafia were involved in CIA's attempts to assassinate Cuban leader Fidel Castro. The documents showed that, in September 1960, the CIA recruited Robert Maheu, an ex-FBI agent and aide to Howard Hughes in Las Vegas, to approach Roselli under the pretense of representing international corporations that wanted Castro dead due to lost gambling interests. Roselli introduced Maheu to mobster leaders Sam Giancana and Santo Trafficante Jr. Supplied with six poison pills from the CIA, Giancana and Trafficante tried unsuccessfully to have people place the poison in Castro's food. Further attempts were canceled soon thereafter due to the Bay of Pigs invasion in April 1961. In 1963, singer Frank Sinatra sponsored Roselli for membership in the exclusive Los Angeles Friar's Club. Soon after his acceptance, Roselli discovered an elaborate card-cheating operation run by one of his Las Vegas friends, Maurice Friedman, and asked for his cut.

During the trial, secret grand jury transcripts were discovered on the defense attorney's table. Cooper eventually pleaded guilty to contempt for possessing the documents. In the 1960s, Immigration and Naturalization Service had also tried to deport Roselli, although were unsuccessful. 1970s On June 24 and September 22, 1975, Roselli testified before the 1975 U.S. Senate Select Committee on Intelligence (SSCIA) led by Idaho Senator Frank Church about the CIA plan to kill Castro, Operation Mongoose. Shortly before Roselli testified, an unknown person shot and killed Giancana in the basement of his Illinois home. This happened just days before Giancana was to testify before the committee. Giancana's murder supposedly prompted Roselli to permanently leave Los Angeles and Las Vegas for Miami, Florida. On April 23, 1976, Roselli was called before the committee to testify about a conspiracy to kill President Kennedy. Three months after his first round
