 The hearings had positive benefits for other key participants as well . The Kennedy @-@ Ives bill was Senator John F. Kennedy 's most important legislative accomplishment , and although it was not enacted into law many Senators nonetheless revised their opinion and now saw him as a serious legislator . This helped remove a major obstacle to Kennedy 's political aspirations . Kennedy also used the publicity he gained from the Select Committee 's work to launch his own presidential bid in 1960 . The work of the Select Committee also was a key turning point in the Senate career of John L. McClellan . McClellan devoted significant time and resources of the Permanent Subcommittee on Investigations ( of which he was chair ) to pushing anti @-@ organized crime agenda in 1960s , and his efforts kept the issue alive despite the prominence of other issues such as the civil rights movement and Vietnam War . When limited jurisdiction over organized crime was transferred to the Committee on Government Operations after the disbandment of the Select Committee , Senator McClellan held a number of sensational hearings on organized crime from 1960 to 1964 which became known as the Valachi Hearings . In 1962 , McClellan published his own account of the Select Committee 's activities and findings in the book Crime Without Punishment . The senator sponsored several pieces of important anti @-@ crime legislation in the 1960s and early 1970s , including the Omnibus Crime Control and Safe Streets Act of 1968 and the Organized Crime Control Act of 1970 ( part of which contains the highly influential Racketeer Influenced and Corrupt Organizations Act ) .
