Diana Harshbarger

Early life and career

Harshbarger was born in Kingsport, Tennessee, and raised in nearby Bloomingdale. She is the first person in her family to graduate from high school. She attended East Tennessee State University and earned her Doctor of Pharmacy from Mercer University.

Harshbarger has been a licensed pharmacist since 1987. She and her husband, Bob, operate Premier Pharmacy, a compounding pharmacy.

U.S. House of Representatives

Election

After six-term incumbent and fellow Republican Phil Roe opted to retire from the United States House of Representatives, Harshbarger announced her candidacy to succeed him in the United States House of Representatives for Tennessee's 1st congressional district. She won the 17-way August 5 Republican primary and defeated Democratic nominee Blair Walsingham in the November general election. She had effectively clinched a seat in Congress with her victory in the primary, since the 1st is one of the few ancestrally Republican districts in the South; it has been in Republican hands for all but four years since 1861, and Democrats have garnered as much as 40% of the vote only twice since 1898. When Harshbarger took office on January 3, 2021, she became the fifth woman elected to Congress from Tennessee, but only the third who was not a stand-in for her husband, after Diane Black and Marsha Blackburn. The 1st historically gives its incumbents very long tenures in Washington; Harshbarger is only the ninth person to hold the seat in 100 years.

Harshbarger focused her campaign on fixing the opioid crisis, advocating anti-abortion legislation, and protecting religious freedom. She also highlighted American dependence on Chinese pharmaceutical imports as an issue of national security. During the Republican primary, her opponents criticized her over her alleged involvement with American Inhalation Medication Specialists (AIMS), a business her husband ran that sold mislabeled pharmaceuticals from China. In 2013 Robert Harshbarger pleaded guilty to fraud charges related to the company and was sentenced to 48 months in federal prison, in addition to over $800,000 in restitution and over $400,000 in asset forfeiture. Harshbarger's campaign said she had no involvement with AIMS, despite corporate records to the contrary.

Harshbarger declined to debate her competitors during the primary and general elections.

Tenure

On January 6, 2021, supporters of President Donald Trump stormed the U.S. Capitol during debate. Lawmakers fled to an undisclosed location for safety. Later that evening, Harshbarger joined 139 other Republican House members in voting to sustain objections to the certification of the results of the 2020 U.S. presidential election, based on claims of voter fraud.

In August 2021, Business Insider reported that Harshbarger had violated the Stop Trading on Congressional Knowledge (STOCK) Act of 2012, a federal transparency and conflict-of-interest law, by failing to properly disclose over 700 stock trades worth between $728,000 and $10.9 million.

Harshbarger supported efforts to impeach President Joe Biden. In September 2021 Harshbarger co-sponsored a resolution by Marjorie Taylor Greene to impeach President Joe Biden over the withdrawal of United States troops from Afghanistan. In May, 2023, she co-sponsored a resolution by Greene to impeach Biden over his handling of security at the United States–Mexico border. Also in May 2023, she co-sponsored Greene's resolutions to impeach Attorney General Merrick Garland, FBI director Christopher Wray, Secretary of Homeland Security Alejandro Mayorkas, and U.S. attorney for D.C. Matthew M. Graves.

Harshbarger was among the 71 Republicans who voted against final passage of the Fiscal Responsibility Act of 2023 in the House.

In 2024, Harshbarger voted against the $60 billion military aid package for Ukraine; The Washington Post reported that some of the funding would have supported defense jobs in her constituency.

On a podcast in 2025, Harshbarger called Representative Al Green a racist term and made a baseless accusation that he hides a gun in his cane. In the same podcast, she also used a slur to refer to members of the LGBTQ community.

In February 2026, Harshbarger prayed to the Christian god that "ungodly" persons should be removed from "places of authority".

Political positions

Healthcare

In 2024, Harshbarger spoke against expanded coverage of anti-obesity drugs for Medicaid and Medicare recipients. She said, "Obesity is not a disease. It’s a side effect of different things, like unhealthy eating or whatever. So no, I’m not in favor of that, because it’s going to put us in dire straits and run us out of money."

Foreign policy

In 2025, Harshbarger commented on President Trump's proposal to take over the Gaza Strip and redevelop the area, saying "This is what the leader of the free world looks like" and "Promises made, promises kept".
