The legislative branch of the US Government, or the Congress, represents all of the American states. It consists of two parts: the House of Representatives and the Senate. Each state has two senators, who are elected every 6 years. A senator must be at least 30 years old, a citizen of the United States for 9 years, and live in the state she or he will represent. A representative must be at least 25 years old, a citizen for 7 years, and live in the state.
The job of the Congress is to make laws. The President can veto a bill. The Congress can pass the law anyway if it gets a two-thirds majority vote. The Congress can also declare war. The House of Representatives can also impeach the President.
The executive branch of the government puts the country's laws into effect. The President of the United States is a member of the executive branch. The President must be at least 35 years old, and be a natural citizen of the USA. In addition, he must have lived in the US for at least 14 years, and be a civilian. The President is elected every four years and cannot serve more that two terms. The Vice-President of the USA is president of the Senate. The President can also ask the Congress to declare war. He also appoints the justices to the Supreme Court. He must do his job according to the Constitution, or he may be impeached.
