DesJarlais, Scott

Scott DesJarlais represents Tennessee's 4th congressional district and serves as chair of the House Armed Services Subcommittee on Strategic Forces. As subcommittee chair, he shapes oversight and legislation governing the nation's nuclear arsenal, strategic deterrence, and military space capabilities—areas where Congress exercises significant control over defense spending and policy direction. His role gives him authority to schedule hearings, direct investigations, and advance legislation within his subcommittee's jurisdiction.

DesJarlais brings a medical background to his legislative work. A physician trained at the University of South Dakota School of Medicine, he moved to East Tennessee in 1993 to practice medicine as a generalist before entering Congress in 2011. While his medical expertise is not directly aligned with defense and nuclear policy, his service on both the Armed Services Committee and the Agriculture Committee reflects his representation of a rural, economically diverse district spanning East and Middle Tennessee.

As a conservative Republican, DesJarlais has sponsored legislation across multiple policy areas, including measures on animal welfare, border security, student loan accountability, and military affairs. His sponsored bills demonstrate engagement with both his district's agricultural interests and broader national security concerns. His committee assignments position him to influence defense spending priorities and military readiness strategies that affect both national security and his constituents' economic interests.
