in 1994 when, after spending forty years in the minority, the Republicans regained control of the House with the "Contract with America", an idea spearheaded by Minority Whip Newt Gingrich. Speaker Gingrich would regularly clash with Democratic President Bill Clinton, leading to the United States federal government shutdown of 1995 and 1996, in which Clinton was largely seen to have prevailed. Gingrich's hold on the leadership was weakened significantly by that and several other controversies, and he faced a caucus revolt in 1997. After the Republicans lost House seats in 1998 (although retaining a majority) he did not stand for a third term as speaker. His successor, Dennis Hastert, had been chosen as a compromise candidate since the other Republicans in the leadership were more controversial. Hastert played a much less prominent role than other contemporary speakers, being overshadowed by House Majority Leader Tom DeLay and President George W. Bush. The Republicans came out of the 2000 elections with a further reduced majority but made small gains in 2002 and 2004. The periods of 2001–2002 and 2003–2007 were the first times since 1953–1955 that there was single-party Republican leadership in Washington, interrupted from 2001 to 2003 as Senator Jim Jeffords of Vermont left the Republican Party to become independent and caucused with Senate Democrats to give them a 51–49 majority. In the 2006 midterm elections, the Democrats won a majority in the House. Nancy Pelosi became speaker when the 110th Congress convened on January 4, 2007, making her the first woman to hold the office. During the 111th Congress, Pelosi was the driving force behind several of President Barack Obama's major initiatives that proved controversial, and the Republicans campaigned against the Democrats' legislation by staging a "Fire Pelosi" bus tour and regained control of the House in the 2010 midterm elections. John Boehner was elected speaker when the 112th Congress convened on January 5, 2011, and was subsequently re-elected twice, at the start of the 113th and 114th Congresses. On both of those occasions his remaining in office was threatened by the defection of several members from his own party who chose not to vote for him. Boehner's tenure as speaker, which ended when he resigned from Congress in October 2015, was marked by multiple battles with the conservatives in his own party related to "Obamacare", appropriations, among other political issues. This intra-party discord continued under Boehner's successor, Paul Ryan.
