Congress is the legislative arm of our government and its job is to make laws. Congress is made up of two houses: the Senate (upper) and the House of Representatives (lower). Each state has two senators in the Senate. The number of representatives a state has is determined by its population. While the house and senate are similar, there are some differences.
