Born on January 1, 1960, Harshbarger has emerged as a prominent political leader representing Tennessee's 1st congressional district, which encompasses the northeastern Tri-Cities region.
With a strong background in healthcare, Harshbarger leveraged her professional experience as a pharmacist into public service. Her deep roots in Tennessee and commitment to conservative values propelled her political career, leading to her successful election to the U.S. House of Representatives in 2020, where she succeeded incumbent representative Phil Roe. A staunch supporter of former President Donald Trump, she quickly distinguished herself as a principled conservative voice in Congress.
As a member of both the Freedom Caucus and Republican Study Committee, Harshbarger has been a consistent advocate for limited government, fiscal responsibility, and traditional conservative principles.
