James R. Hoffa, then Vice-President of the Teamsters Union, testifies 20 August 1957 in Washington DC before the Senate Rackets Committee. His son, Jimmy Hoffa Jr. was elected 06 December President of the 1. 4 million-strong International Brotherhood of Teamsters labor confederation. His father, the legendary James R. Hoffa headed the Teamsters, one of the two powerful US labor confederations, from 1957 to 1967. He was sent to prison for jury tampering and fraud in the late 1960s and disappeared without a trace in 1975, presumably killed by former Mafia associates.
