While serving in Afghanistan with Operation Enduring Freedom, he stepped on an IED in Kandahar on September 19, 2010, losing both legs and his left index finger, and he received the Bronze Star and Purple Heart. He later earned a Bachelor of Liberal Arts from the Harvard Extension School in 2016.
After his discharge from the Army, Brian Mast worked as an explosives specialist for the Department of Homeland Security and provided explosive and counter-terrorism expertise to the National Nuclear Security Administration from July 2011 to February 2012.
He won the Republican primary for Florida's 18th congressional district on August 30, 2016, with 38% of the vote and defeated Democrat Randy Perkins in the general election with 53%, taking office on January 3, 2017.
After the 2020 redistricting cycle renamed the district the 21st, he won in 2022 with 63.5% and in 2024 with 61.8%. Since 2025 he has chaired the House Foreign Affairs Committee, and he also sits on the Committee on Transportation and Infrastructure.
