Kathryn Christine Cammack (/ˈkæmæk/ KAM-ak; born February 16, 1988)[2] is an American politician and political advisor serving as the U.S. representative for Florida's 3rd congressional district.

A member of the Republican Party, Cammack previously served as deputy chief of staff to her predecessor, Representative Ted Yoho, who retired in 2020.

[6] She earned a Bachelor of Arts degree in international relations from the Metropolitan State University of Denver and a Master of Science in national defense and strategic studies from the Naval War College.

[5][11] Cammack has said that her family's experience with the federal Home Affordable Modification Program in 2011 inspired her interest in politics.

[27][28] Cammack ran for chair of the Republican Study Committee but later withdrew her bid for the position and endorsed Kevin Hern.

Cammack won the general election with 62.5% of the vote to Democratic nominee Danielle Hawk's 36.3% and NPA Linda Brooks's 1.2%.

[42] On the House floor, she said the January 6 attacks "furthermore resolved" her objection to the certification process and that, as representatives of the people, members of Congress must stand for a free and fair election.

[43] Numerous inquiries have found no evidence that the election was unfree or unfair to an extent that changed its outcome.

[67] On July 22, 2021, Cammack claimed on the House floor that NGOs transport undocumented migrants around the country at U.S. government expense.

[69] White House press secretary Jen Psaki said that under the Flores Settlement Agreement, the U.S. is required to provide adequate and age-appropriate food, "hence formula for kids under the age of 1.

"[70] During an interview with Sean Hannity on Fox News, Cammack showed pictures of baby formula she said she had received from a CBP agent.

Tommy Christopher wrote that some of the images used in Cammack's interview with Hannity were not of baby formula but of powdered milk for children older than one.

[73][74] Cammack has said it is reassuring that the Capitol Police are expanding into Florida and will work with local law enforcement.

[75] Cammack has called the Equality Act—a bill that would amend the Civil Rights Act of 1964 (including titles II, III, IV, VI, VII, and IX) to prohibit discrimination on the basis of sex, sexual orientation and gender identity in employment, housing, public accommodations, education, federally funded programs, credit, and jury service—a "farce" that will strip people of faith and private organizations of the right to decide for themselves how to live, work, and conduct business.

[78] Cammack wrote that she supported the bill because, under the Fourteenth Amendment, the law cannot treat one group of citizens differently from another.

[79] Cammack was among the 71 House Republicans who voted against final passage of the Fiscal Responsibility Act of 2023, which suspends the debt limit until January 2025.
