Brian Mast

Representative Brian Mast (R-FL) has served Florida's 21st district since 2017, bringing his background as a combat veteran and former Army bomb technician who lost both legs in Afghanistan to his work on the House Foreign Affairs and Transportation committees. Known for his environmental advocacy in protecting the Everglades and Indian River Lagoon, Mast has positioned himself as a conservation-minded Republican willing to break with party orthodoxy on ecological issues. His trading activity shows 47 disclosed transactions between June 2018 and March 2024, with an estimated volume between $711K and $2.1M, concentrated in volatile securities including cannabis company Tilray (TLRY), telemedicine firm SmileDirectClub (SDC), and electric vehicle maker NIO. Mast's trading activity has gone dormant recently with no transactions recorded in the past 90 days, and his portfolio reveals a pattern of engagement with speculative, high-growth sectors rather than traditional blue-chip holdings.
