the presiding officer of the house is the speaker of the house constitution
Speaker of the United States House of Representatives The Speaker of the House is the presiding officer of the United States House of Representatives. The office was established in 1789 by Article I, Section 2 of the United States Constitution. The Speaker is the political and parliamentary leader of the House of Representatives, and is simultaneously the House's presiding officer, leader of the body's majority party, and the institution's administrative head. Speakers also perform various other administrative and procedural functions. Given these several roles and responsibilities, the Speaker usually does not personally preside over debates. That duty is instead delegated to members of the House from the majority party. Neither does the Speaker regularly participate in floor debates or vote.
Speaker of the United States House of Representatives The House of Representatives elects the Speaker of the House on the first day of every new Congress and in the event of the death, resignation or removal from the Chair of an incumbent Speaker. The Clerk of the House of Representatives requests nominations: there are normally two, one from each major party (each party having previously met to decide on its nominee). The Clerk then calls the roll of the Representatives, each Representative indicating the surname of the candidate the Representative is supporting. Representatives are not restricted to voting for one of the nominated candidates and may vote for any person, even for someone who is not a member of the House at all. They may also abstain by voting "present".[5]
