Biography

Brian Mast is the incumbent Republican U.S. Representative for the 21st District, first elected in 2016. A U.S. Army veteran who served more than 12 years as a bomb disposal expert, he lost both legs to an improvised explosive device in Afghanistan. He chairs the House Foreign Affairs Committee and also sits on the Transportation and Infrastructure Committee.[1][2]

According to Wikipedia, Mast was born and raised in Grand Rapids, Michigan, in 1980 and graduated from South Christian High School in 1999.[3] He attended Palm Beach Atlantic University, American Military University and the Harvard University Extension School, and Wikipedia reports that he received a Bachelor of Liberal Arts from Harvard Extension School in 2016.[1][3] His official biography says he served in the U.S. Army for more than 12 years and earned the Bronze Star Medal, the Army Commendation Medal for Valor, the Purple Heart Medal and the Defense Meritorious Service Medal.[2]

Mast worked as a bomb disposal expert under Joint Special Operations Command in Afghanistan, where the last improvised explosive device he found cost him both legs; Wikipedia dates the injury to 2010.[2][3] He stayed on active duty during his recovery and provided expertise to the National Nuclear Security Administration and the Bureau of Alcohol, Tobacco, Firearms and Explosives. After retiring from the Army he worked as an explosive specialist for the Department of Homeland Security.[2] According to his official biography, he volunteered alongside the Israel Defense Forces after earning his Harvard degree, which Wikipedia dates to January 2015.[2][3]

Mast won the open 21st District seat in November 2016, defeating Democrat Randy Perkins, independent Carla Spalding and write-in candidate Marilyn Holloman, after Rep. Patrick Murphy left to run for the U.S. Senate.[1] He is now in his fifth term. He has chaired the House Foreign Affairs Committee since 2025 and serves on the Transportation and Infrastructure Committee, where his official biography lists Lake Okeechobee water quality among his priorities.[2][1] According to that biography, he lives in Fort Pierce with his wife, Brianna, and their four children. His August 2026 Republican primary was canceled and he advanced unopposed.[2][1]
