Who leads the house of representatives, and how is this role different from that of the leader of the senate

The leader of the House is the Speaker of the House. The Speaker is a House member who is elected by the other representatives. Their role is different from that of the leader of the senate because the leader of the senate is the vice president of the US. Their role is mostly ceremonial and only vote in a tie. The speaker, however, has the power to recognize or ignore members who wish to speak on the floor. They also can interpret House rules, which allows the Speaker to determine which legislation is assigned to each committee. Plus, they are allowed to appoint members of special and conference committees; and to delay or speed up the legislative calendar.
