Mafia bosses planned to compromise" Bobby and Edward Kennedy at a New York party in a plot involving Frank Sinatra and Marilyn Monroe, according to FBI documents. The intention was to work through "associates" of the two stars to lure the Kennedys, as well as Peter Lawford, their British actor brother-in-law and fellow member of Sinatra's "rat pack", into actions they would regret. The plot is thought to have fizzled out, but it is consistent with other accounts of the extraordinary links between [the Kennedys], the country's biggest stars and organised crime. Monroe, who died in 1962, allegedly had affairs with both Bobby Kennedy and John F Kennedy. It has previously been claimed that she passed on pillow talk from Bobby Kennedy to Sinatra who in turn passed them on to his mafia friends. As attorney general Robert Kennedy launched several investigations into the mob which it may have felt warranted a measure of retribution. From early on in his four-decade career in the senate, Edward Kennedy, the youngest of the three brothers, was known for his affairs with women and extravagant drinking habits. Papers released earlier this year the library of former president Richard Nixon showed that in the early 1970s he discussed with the aides the possibility of discrediting Kennedy by leaking news of his infidelities. Agents in Milwaukee took the information from an unidentified source "who had furnished reliable information in the past," according to the memo. However, the informant could not verify the truth of any of the rumor's details.
