Congressperson

A congressman or congresswoman (generically, congressperson) is a politician that is a member of a congress. In the United States, a congressman specifically refers to a member of the country's House of Representatives. Technically, senators (members of the Senate, the other house of the U.S. Congress) are also congressmen, but are rarely referred to as such to avoid confusion.

In countries with a "Parliament" rather than a "Congress," MP (Member of Parliament) is used instead.
