is the speaker of the house part of the cabinet
Cabinet of the United States The Cabinet includes the Vice President and the heads of 15 executive departments, listed here according to their order of succession to the Presidency. These 15 positions are the core "cabinet member" seats, as distinct from other Cabinet-level seats for other various top level White House staffers and heads of other government agencies, none of whom are in the presidential line of succession and not all of whom are Officers of the United States.[8] Note that the Speaker of the House and the President pro tempore of the Senate follow the Vice President and precede the Secretary of State in the order of succession, but both are in the legislative branch and are not part of the Cabinet.
Speaker of the United States House of Representatives In 1997, several Republican congressional leaders tried to force Speaker Newt Gingrich to resign. However, Gingrich refused since that would have required a new election for Speaker, which could have led to Democrats along with dissenting Republicans voting for Democrat Dick Gephardt (then Minority Leader) as Speaker. After the 1998 midterm elections where the Republicans lost seats, Gingrich did not stand for re-election. The next two figures in the House Republican leadership hierarchy, Majority Leader Richard Armey and Majority Whip Tom DeLay, chose not to run for the office. The chairman of the House Appropriations Committee, Bob Livingston, declared his bid for the speakership, which was unopposed, making him Speaker-designate. It was then revealed, by Livingston himself, who had been publicly critical of President Bill Clinton's perjury during his sexual harassment trial, that he had engaged in an extramarital affair. He opted to resign from the House, despite being urged to stay on by House Democratic leader Gephardt. Subsequently, chief deputy whip Dennis Hastert was selected as Speaker. The Republicans retained their majorities in the 2000, 2002, and 2004 elections.
