US House of Representatives
Also referred to as a congressman or congresswoman, each representative is elected to a two-year term serving the people of a specific congressional district. The number of voting representatives in the House is fixed by law at no more than 435, proportionally representing the population of the 50 states. Currently, there are five delegates representing the District of Columbia, the Virgin Islands, Guam, American Samoa, and the Commonwealth of the Northern Mariana Islands. A resident commissioner represents Puerto Rico. Here's the list: US House of Reps
US Senators
The United States Senate is the upper house of the bicameral legislature of the United States, and together with the United States House of Representatives comprises the United States Congress. The composition and powers of the Senate are established in Article One of the U.S. Constitution. Each U.S. state is represented by two senators, regardless of population. Senators serve staggered six-year terms.
The Senate has several exclusive powers not granted to the House, including consenting to treaties as a precondition to their ratification and consenting or confirmation of appointments of Cabinet secretaries, federal judges, other federal executive officials, military officers, regulatory officials, ambassadors, and other federal uniformed officers, as well as trial of federal officials impeached by the House. The Senate is both a more deliberative and more prestigious body than the House of Representatives, due to its longer terms, smaller size, and statewide constituencies, which historically led to a more collegial and less partisan atmosphere. The Senate has been described by some members of the American media as the "world's greatest deliberative body." Here's the list US Senate
