Imagine that the U.S. government is a chair with three legs.
One leg is the executive – the president and all the people who carry out the country's laws.
Another leg is the judiciary – Supreme Court justices and judges on other federal courts. They decide what the law means.
And another leg is the legislature – the elected officials who make laws. Another word for the legislature is Congress.
What does Congress do?
The first article of the U.S. Constitution describes the powers Congress has.
First, Congress makes federal laws. These are laws everyone in the country must follow.
Historically, Congress has made laws related to Native Americans, slavery and many other issues. They include immigration, business, banking, health, education, voting, foreign relations, and the environment.
Congress has other important powers, too. It can raise money, spend money, and borrow money. It approves Supreme Court justices. It can impeach and remove a president from office. It also can declare war.
Wait, so what is the Senate? And the ‘House'?
When they are talking about U.S. lawmakers or lawmaking, Americans sometimes use the term "Congress." And sometimes they talk about the two parts of Congress: the Senate and the House of Representatives or ‘House,' for short.
Members of the Senate are called senators. Members of the House are called House members, representatives, congressmen or congresswomen.
The Congress has a lot more House members than Senators. That is because voters in each of the 50 states elect only two senators ... and as many House members as permitted by law.
Under the Constitution, House seats are based on the size of a state's population. For example, California, the most populous state, has 53 House members. Wyoming, the least populous state, has only one. But both California and Wyoming have two senators.
In total, the House has 435 voting members, while the Senate has 100 voting members, for a total of 535 lawmakers. They all meet in the Capitol building in Washington, DC.
When Americans want to block, create or change a law in the U.S., they are often urged to contact their member of Congress. Some Americans also campaign for candidates to be elected to the House or Senate. In general, citizens of other countries are not permitted to donate money to members of Congress or lead campaign efforts.
