The United States Congress has two chambers, one called the Senate and the other called the House of Representatives (or “House” for short) which share the responsibilities of the legislative process to create federal statutory law. They occupy opposite ends of the Capitol Building.

About the Senate

The United States’s 50 states each elect two senators for staggered six-year terms. A senator represents between 1 and 37 million people, depending on their state’s population.

The day-to-day activities of the Senate are controlled largely by the political party holding the most seats, called the “majority party.” Here is a count of senators by party:
