The names of the two houses of Congress are the Senate and the House of Representatives. The Senate has 100 members, whereas the House of Representatives consists of 435 members. Each state has two senators; the number of representatives from each state is based on the population of the state.
Congress makes the laws for the nation. Both houses of Congress must approve the same bill by a majority before it can be put before the president to sign into law.
The leading member of the House of Representatives is the speaker of the House; the leader of the Senate is the vice president, who can break ties that occur during Senate voting. Senators serve six-year terms; representatives are elected every two years. The requirements for running for the Senate are more stringent than those for the House of Representatives.
