Boxer won the 1992 election for the U.S. Senate. Running for a third term in 2004, she received 6.96 million votes, becoming the first person to ever get more than 6 million votes in a Senate election and set a record for the most votes in any U.S. Senate election in history, until her colleague, Dianne Feinstein, the senior senator from California, surpassed that number in her 2012 re-election. Boxer and Feinstein were the first female pair of U.S. Senators representing any state at the same time. Boxer was the ranking member of the Environment and Public Works Committee and the vice chair of the Select Committee on Ethics. She was also the Democratic Chief Deputy Whip.
