Which member of the Senate is often seen as leading the chamber in the absence of the Vice President?

The President pro tempore of the Senate holds a significant ceremonial position, often seen as the main leader of the Senate when the Vice President is not present. This role is traditionally filled by the most senior member of the majority party. The President pro tempore presides over the Senate’s sessions, maintains order, and can take part in legislative duties such as assigning bills to committees.

In contrast, the Senate Majority Leader primarily leads the legislative agenda of the majority party and coordinates legislative efforts but does not have the same formal authority over the chamber as the President pro tempore does. The Minority Leader represents the interests of the minority party, and the Sponsor of the Senate is not a recognized leadership position within the Senate. Hence, the designation of the President pro tempore as the leader of the chamber in the absence of the Vice President is well established and reflects the structure of Senate leadership.
