Members of the United States Congress

The US Congress is the collection of members of both houses of its legislature - the Senate and the House of Representatives. Members of the House of Representatives are elected to serve a two-year term representing the people of each person's district. Each state, regardless of its size, has at least one representative. Each member of the Senate is elected to serve a six-year term representing the people of that person's state. Each state, regardless of its size, has two senators. Senatorial terms are staggered, so every two years approximately one-third of the Senate is up for election. Each staggered group of one-third of the senators is called a 'class'. No state has both its senators in the same class. Source: Wikipedia
