title of main officer in house of representatives
United States House of Representatives The presiding officer is the Speaker of the House, who is elected by the members thereof and is therefore traditionally the leader of the controlling party. The Speaker and other floor leaders are chosen by the Democratic Caucus or the Republican Conference, depending on whichever party has more voting members. The House meets in the south wing of the United States Capitol.
Presiding Officer of the United States Senate The Presiding Officer of the United States Senate is the person who presides over the United States Senate and is charged with maintaining order and decorum, recognizing members to speak, and interpreting the Senate's rules, practices, and precedents. Senate presiding officer is a role, not an actual office. The actual role is usually performed by one of three officials: the Vice President; an elected United States Senator; or, in special cases, the Chief Justice. Outside the constitutionally mandated roles, the actual appointment of a person to do the job of presiding over the Senate as a body is governed by Rule I of the Standing Rules.
