Who is the chief presiding officer of the House of Representatives, elected at the beginning of every Congress?

The chief presiding officer of the House of Representatives is the Speaker of the House. The Speaker is elected at the beginning of each Congress and holds a significant leadership role within the House. This position involves overseeing proceedings, ensuring that rules are followed during debates, and managing the legislative agenda. The Speaker is typically a member of the majority party and plays a crucial role in coordinating the actions of other members and representing the House in interactions with the Senate and the President.

The other roles mentioned, such as the House Majority Leader and the House Minority Leader, have important functions in organizing their respective parties within the House but do not hold the same authoritative position as the Speaker. The Senate Majority Leader, while a significant leader in the Senate, does not serve the House of Representatives and therefore cannot fulfill the role described in the question.
