Beck was indicted for tax evasion on May 2, 1957. Beck's legal troubles led him to retire and Hoffa to win election to the union presidency. Support for Beck among the membership evaporated. Beck announced on May 25 he would not run for re-election in October. The announcement created chaos among the union leadership, and despite additional indictments Hoffa announced he would seek the presidency on July 19. Rank-and-file support for Hoffa was strong, although there were some attempts to organize an opposition candidate. Hoffa's opponents asked a federal judge to postpone the election, but the request was granted only temporarily and Hoffa was duly elected General President of the union on October 4, 1957. Beck offered to retire early to allow Hoffa to take control of the union in December. A federal district court barred Hoffa from taking power unless he was acquitted in his wiretapping trial. The ruling was upheld by a court of appeals, but the trial ended in a hung jury on December 19, 1957, and Hoffa assumed the presidency on February 1, 1958. The worsening corruption scandal led the AFL–CIO to eject the Teamsters. AFL–CIO President George Meany, worried that corruption scandals plaguing a number of unions at the time might lead to harsh regulation of unions or even the withdrawal of federal labor law protection, began an anti-corruption drive in April 1956. New rules were enacted by the labor federation's executive council that provided for the removal of vice presidents engaged in corruption as well as the ejection of unions considered corrupt. The McClellan Committee's investigation only worsened the dispute between the AFL–CIO and the Teamsters. In January 1957, the AFL–CIO proposed a new rule which would bar officers of the federation from continuing to hold office if they exercised their Fifth Amendment rights in a corruption investigation. Beck opposed the new rule, but the Ethical Practices Committee of AFL–CIO instituted the rule on January 31, 1957. The Teamsters were given 90 days to reform, but Beck retaliated by promising more raids on AFL–CIO member unions if the union was ousted. Beck's opposition prompted a successful move by Meany to remove Beck from AFL–CIO executive council on grounds of corruption. After extensive hearings and appeals which lasted from July to September 1957, the AFL–CIO voted on September 25, 1957, to eject the Teamsters if the union did not institute reforms within 30 days.
