Virginia has sent senators to the U.S. Senate since 1789. Its Senate seats were declared vacant in March 1861, due to its secession from the Union, but senators representing its western counties continued to sit until March 1865. Virginia's Senate seats were again filled from January 1870. Virginia's current senators are Democrats Mark Warner and Tim Kaine. Harry F. Byrd was Virginia's longest-serving senator (1933–1965).
