FILE - In this Aug. 29, 1957 file photo, Sen.Strom Thurmond, D-SC, gives a wave as he leaves the Senate chamber at end of his 24 hour, 19 minute one-man filibuster against the compromise civil rights bills. The effort went for naught however, as less than two hours later, the measure was passed 60-15. Filibusters, taken from a Dutch word that means “pirate,” involve any delaying tactic that blocks the Senate from voting on legislation or a nomination. (AP Photo)
