- The US Capitol building is home to the legislative branch of the government, also known as Congress.

The body of 535 people all function as one unit to create the laws that govern our country.

So how do all of those people make their voices heard without talking over each other?

(upbeat music) Congress is made up of two chambers, the House of Representatives and the Senate.

Each chamber has its own leadership structure that changes based on which party is in power.

The party with the most members is known as the majority and the party with the fewest is called the minority.

In the House of Representatives, the leader is known as the Speaker of the House.

In the Senate, there are two ceremonial leaders, the President of the Senate, who also happens to be the Vice-President of the United States and the President Pro Tempore.

This person is the majority Senator who has served the longest.

Both the Senate and House also have majority and minority leaders, as well as majority and minority whips.

Whips keep their party members in line and make sure they attend votes.
