<human>: I'd like to know more about how the US government is structured and how it works.
<bot>: The United States of America is a federal republic composed of 50 states, each with its own legislature, executive branch, and judicial system. The federal government consists of three branches: legislative, executive, and judicial. Each state has two senators in the upper house of Congress, and one member from each state in the lower house. The president is elected by the people for four years, and can be re-elected once. The Supreme Court is made up of nine judges who are appointed for life by the president.
