Mark was first elected in 2015 to represent the people of VA's 45th District (Alexandria, Arlington, Fairfax). Mark grew up in Tennessee, earned an economics degree at Harvard University, and graduated from Yale Law School. He worked briefly as a Nazi hunter, a Jewish historian, and an inner-city school teacher before becoming a trial attorney in Los Angeles. In December 2000, Mark was hired by the Congressional Black Caucus to challenge Bush’s Florida electors, when the US Supreme Court refused to allow Florida’s ballots to be counted. Mark then moved to Alexandria, VA, to work for Massachusetts Congressman Barney Frank as his legislative counsel, where he handled Judiciary, Financial Services, and Homeland Security matters. In 2010, Mark wrote the bill that became DC’s Marriage Law for same-sex couples and defended it in court. In the House of Delegates, Mark formed the VA Transparency Caucus and persuaded the General Assembly to livestream and archive all of its committee proceedings and to record all of its votes. His legislative record includes measures to help workers; to prevent domestic abuse, sexual violence, and gun violence; to promote racial justice, LGBTQ+ civil rights, and election reform; and to mitigate climate change.
