As a senator, Murray has been a part of party leadership since 2001, having served as chair of the Democratic Senatorial Campaign Committee, Democratic Conference secretary, and assistant Democratic leader. Before assuming her current roles, Murray previously chaired the Veterans' Affairs, Budget, and Health, Education, Labor and Pensions Committees. Murray garnered national attention in 2013, when she and Republican representative Paul Ryan announced that they had negotiated a two-year, bipartisan budget, known as the Bipartisan Budget Act of 2013. Murray is currently the third-most senior senator, the most senior Senate Democrat, the second-longest serving woman to ever serve in the Senate, and the dean of Washington's congressional delegation.
