Claim: In the United States House of Representatives's 110th Congress, held during George W. Bush's second term, though committee chairmanship is associated with seniority, party leadership is not.
Evidence: The 110th United States Congress was a meeting of the legislative branch of the United States federal government, between January 3, 2007, and January 3, 2009, during the last two years of the second term of President George W. Bush. Committee leadership in the House is often associated with seniority, especially in the Democratic Caucus. Party leadership in the House is not strictly associated with seniority.
