Tennessee special election live: Trump backs Republican Matt Van Epps

Mark Green, a physician and retired U.S. Army surgeon, represented Tennessee’s 7th congressional district from 2019 until his resignation in 2025. A Republican, Green chaired the House Committee on Homeland Security from 2023 to 2025 before leaving Congress to enter the private sector.

A West Point graduate, Green served as an infantry officer before earning his medical degree at Wright State University. He became a flight surgeon with the Army’s elite 160th Special Operations Aviation Regiment, participating in missions in Afghanistan and Iraq, including Operation Red Dawn, which captured Saddam Hussein. He later authored a book about the experience.

After retiring from the military in 2006, Green founded Align MD, a hospital staffing company, and launched a medical foundation providing care to underserved communities. He entered politics in 2012, winning a Tennessee Senate seat, where he championed legislation to repeal the state’s Hall Income Tax and expand protections for veterans and small businesses.

Green was elected to Congress in 2018, succeeding Marsha Blackburn, and won reelection three times. His tenure included a brief bid for House Speaker in 2023 and leadership on homeland security issues. He announced his resignation in June 2025 after the passage of the “One Big Beautiful Bill Act,” ending his congressional career on July 20.
