The Senate of Virginia is the upper lawmaking house of the Virginia General Assembly. Like its counterpart - the House of Delegates - the Senate drafts and debates legislation that eventually is signed into state law by the Governor. Some 40 senators comprise the Senate and are led by the Lieutenant Governor of Virginia. Senators are elected every four years by state residents in their respective districts. Senate committees - including agriculture, education, health, and social services - originate bills that are then passed on to the full Senate for a vote.
