1964: Teamsters president Jimmy Hoffa is convicted of two counts of jury tampering, which he committed during a 1962 case that charged him with extorting a million-dollar union payoff from a haulage company. He would receive an eight-year prison sentence and a $10,000 fine. Later in the year, he was convicted of fraud in a separate case, receiving another five years. After his appeals process had run out, he entered prison in 1967, but would end up serving just four years of his 13-year sentence, with President Richard Nixon pardoning him in 1971 on the condition that he resign the Teamsters' presidency and be banned from participating in union activities until 1980. Hoffa disappeared in 1975 as he was trying to regain power.
