Lee has represented the Virginia 50th District since 2017.

Lee was an active member of the Manassas City Democratic Committee, and spends much of his time working as a community organizer and activist — particularly in the areas of affordable housing and worker protections. He is also a graduate of the Sorensen Institute of Political Leadership. The Carter family are involved members of the Bull Run Unitarian Universalist congregation in Manassas.

Lee joined the Marine Corps during the beginning of the 'Global War on Terror', and worked in technological repair in a Special Operations-capable support unit, completing tours in the Middle East and the Mediterranean. His unit was also one of the first to respond to Haiti, following the devastating earthquake in 2010.
