Mark Warner is an American businessman and politician serving as the senior United States senator from Virginia since 2009. The second wealthiest member of Congress at $214.1 million worth, he is known for his involvement in telecommunications-related venture capital during the 1980s. He started volunteering in Democratic campaigns when he was attending college and gladly states that he “majored in Washington, D.C.” He served as Chair of Virginia’s Democratic Party between 1993 and 1995. Following a failed attempt at the U.S. Senate in 1996, he won the 2001 Virginia gubernatorial election and served as the 69th governor of Virginia from 2002 to 2006. He has been serving as the Vice Chair of the Senate Democratic Caucus since 2017, and after serving as the Vice Chair of the Senate Intelligence Committee in 2017-21, he was appointed its chair in 2021. He was expected to pursue the Democratic nomination in the 2008 U.S. presidential election, but declined as it would disrupt his family life.
