organizing of TDU and Carey. Carey was later ousted as union president by U.S. government officials. A re-run election in 1998 saw Hoffa and the Unity Slate easily defeat TDU candidate Tom Leedham 54.5 percent to 39.3 percent (with 28 percent turnout). Hoffa was re-elected over Leedham (again running on the TDU platform) in 2001, 64.8 percent to 35.2 percent. Leedham challenged Hoffa and the Hoffa Unity Slate a third time in 2006, losing 65 percent to 35 percent (with 25 percent turnout). Hoffa faced TDU candidate Sandy Pope, a local union president, in 2011. Also running, with a full slate of officer and vice presidential candidates, was former Hoffa supporter and former national vice president Fred Gegare. Hoffa again easily won re-election, earning 60 percent of the vote to Gregare's 23 percent and Pope's 17 percent. The Hoffa Unity Slate also won all five regional vice presidencies, although the slate's support declined across the board. Hoffa won reelection once more in 2016, this time against Teamsters United candidate Fred Zuckerman, but by a much narrower margin of 52 to 48 percent. The 2016 election was also the first time Hoffa-allied candidates lost regional vice presidencies to the Teamsters United reform slate. In the 2021 election, Hoffa did not run for re-election. The Teamsters United slate, aligned with Teamsters for a Democratic Union, ran against the Teamsters Power Slate, endorsed by Hoffa. The Teamsters United slate, led by Sean O'Brien, won the election. O'Brien and his slate were sworn into office on March 22, 2022, at Teamsters headquarters in Washington, D.C. On the day his administration was installed, O'Brien fired more than 80 employees at the headquarters. He did not offer any severance or extension of benefits to the terminated staff. The International Brotherhood of Teamsters currently faces charges with the National Labor Relations Board in connection to the terminations. As of November 10, 2022, the union was required to pay eligible terminated employees more than $175,000 as part of a settlement with the District of Columbia Attorney General's Office for violating D.C.
