 In February 1959 , the Select Committee 's attention turned to an investigation of organized crime . McClellan had won yet another one @-@ year extension of the Select Committee 's existence in January , giving it additional time for more investigations . This new focus was a natural outgrowth of the committee 's previous investigations , but it also reflected the committee 's frustration at uncovering no additional scandals like the one which had rocked the Teamsters . Through much of the spring and summer of 1959 , the committee held a series of public hearings which brought a number of organized crime figures to the public 's attention , including Anthony Corrallo , Vito Genovese , Anthony Provenzano , Joey Glimco , Sam Giancana , and Carlos Marcello . Although more muted and less frequent , criticisms of the Select Committee and Robert Kennedy continued . Kennedy 's moralism about labor racketeering , several high @-@ profile critics concluded , even endangered the Constitution . Although McClellan wanted to further investigate organized crime , the Select Committee had reached the limits of its jurisdiction and no further investigations were made .
