Mast, Brian J.

Brian Mast represents Florida's 21st Congressional District, serving in the U.S. House of Representatives since 2017. Before entering politics, he served for over twelve years in the U.S. Army as a bomb disposal technician. During his service in Afghanistan, he was severely injured by an improvised explosive device, resulting in the loss of both his legs. This background as a veteran heavily influences his legislative priorities and his approach to national security and veterans' affairs.

In the House, Mast holds a significant leadership role as the Chairman of the House Committee on Foreign Affairs. He also serves on the Committee on Transportation and Infrastructure, where he participates in subcommittees focused on Aviation, Water Resources and Environment, and the Coast Guard. His legislative work often centers on international relations, such as his efforts to reform USAID branding and oversee United Nations funding. Locally, he is well known for his advocacy on environmental issues through the Stop Poisoning Florida Act, which addresses water quality and toxic algal blooms in his district.
