Kristi Noem Bio
Kristi Lynn Arnold Noem, born on 30 November 1971, is an American politician, rancher, and author who has served since 2025 as the eighth United States Secretary of Homeland Security. A member of the Republican Party, she previously served as the 33rd governor of South Dakota from 2019 to 2025, making her the first woman to hold that office. Before her time in the governor’s mansion, Noem represented South Dakota’s at-large congressional district in the U.S. House of Representatives from 2011 to 2019, and earlier served in the South Dakota House of Representatives from 2007 to 2011. Known nationally for her conservative positions on abortion, gun rights, and immigration, she also gained widespread attention for her largely hands-off response to the COVID-19 pandemic while governor of South Dakota.
Early Life and Background
Kristi Noem was born on 30 November 1971 in Watertown, South Dakota, and raised in the rural community of Castlewood, where she continues to make her home. She is the daughter of Ron Arnold and Corinne Arnold, who raised their family on a working ranch. Growing up around cattle and farming gave Noem an early and lasting connection to agriculture, a background that would later shape both her public image and her political priorities.
Noem attended Hamlin High School in South Dakota before continuing her education at Northern State University and Mount Marty College. She later earned a Bachelor of Arts in Political Science from South Dakota State University in 2012, completing her degree while already serving in public office. Her formal education, combined with years of hands-on work on her family ranch, helped prepare her for a career that bridged rural South Dakota life and statewide politics.
Path to US Politics
Noem’s entry into public life grew out of her involvement in agriculture and her family’s deep roots in rural South Dakota. Alongside her husband Bryon, whom she married in 1992, she ran the family ranch and raised their daughter Kassidy Peters, born in 1994. The experience of balancing farm responsibilities with community leadership motivated her to seek a seat in the South Dakota House of Representatives in 2006, where she served from 2007 to 2011.
During her time in the state legislature, Noem earned a reputation as a conservative voice focused on agricultural issues, limited government, and rural economic development. Her success at the state level positioned her to run for federal office, and in 2010 she won election to the U.S. House of Representatives. Her rapid rise from the statehouse to Congress reflected both her policy priorities and her appeal to South Dakota voters.
Kristi Noem Career
Early Career (2007-2010)
Kristi Noem began her political career in the South Dakota House of Representatives, winning election in 2006 and serving from 2007 to 2011. During this period, she focused on issues affecting farmers, ranchers, and rural communities, establishing herself as a reliable conservative voice in the state legislature. Her work in Pierre laid the groundwork for a successful run for federal office.
In 2010, Noem ran for South Dakota’s at-large congressional seat and won, becoming one of the prominent members of the large 2011 House Republican freshman class. Her election to Congress marked her transition from state-level policymaking to national politics, where she would go on to influence federal debates on spending, energy, and social issues.
U.S. House of Representatives Breakthrough (2011-2019)
Noem was sworn in to the U.S. House of Representatives in January 2011 and quickly rose within the House Republican Conference. The 87-member freshman class elected her as liaison to the House Republican leadership, making her only the second woman to serve in the House GOP leadership. In this role, she pushed for significant cuts to federal spending and helped Speaker John Boehner manage the expectations of the freshman class.
Early in her tenure, Noem established herself as a leading fiscal conservative. In March 2011, she announced the formation of KRISTI PAC, a leadership political action committee, and was named one of 12 regional directors for the National Republican Congressional Committee during the 2012 election cycle. She also served on the House Armed Services Committee from 2013 to 2015, where she worked on the 2014 National Defense Authorization Act and championed issues important to South Dakota’s Ellsworth Air Force Base.
Throughout her eight years in Congress, Noem took firm stances on a wide range of issues. She co-sponsored legislation to federally ban abortion and supported a 2015 bill to amend the 14th Amendment to define personhood as beginning at fertilization. She opposed the Affordable Care Act and voted repeatedly to repeal it, while also supporting the Keystone XL Pipeline, offshore oil drilling, and an all-of-the-above energy approach. In 2017, she served on the conference committee that negotiated passage of the Tax Cuts and Jobs Act, which she promoted as providing the average South Dakota family with a $1,200 tax cut. She also backed President Donald Trump’s 2017 executive order on refugee admissions and temporary travel restrictions.
South Dakota Governor Era (2019-2025)
Noem was sworn in as the 33rd governor of South Dakota on 5 January 2019, becoming the first woman to hold the office. As governor, she pursued an ambitious conservative agenda, signing legislation to abolish the state’s concealed-carry permit requirement and to enact additional abortion restrictions. In 2019, she also signed so-called anti-protest legislation, developed in collaboration with TransCanada Corporation in the wake of Keystone Pipeline protests, that created a state fund to cover the costs of policing pipeline protests. The law drew constitutional challenges and led the Pine Ridge Indian Reservation and later several other tribes to ban her from their lands.
Noem’s tenure became nationally defined by her response to the COVID-19 pandemic. She was one of the few governors who did not impose a statewide stay-at-home order or mask mandate, and she used the pandemic period to elevate her national profile, including a speaking slot at the 2020 Republican National Convention. Her administration declined $300 weekly federal unemployment supplements, making South Dakota the only state to do so, and she promoted hydroxychloroquine as a potential treatment. The approach drew both strong support and sharp criticism, particularly after a major outbreak at the Smithfield Foods plant in Sioux Falls and a surge in cases following the 2020 Sturgis Motorcycle Rally.
Beyond the pandemic, Noem’s governorship included several high-profile controversies. In 2020, she summoned a state employee to her office over a denied real estate appraisal license for her daughter, Kassidy Peters, an incident that became the subject of legislative and ethics investigations. In 2019, she launched a widely mocked $449,000 meth awareness campaign titled “Meth. We’re on It.” She also unsuccessfully attempted to locate a government-paid RV park in Custer State Park, pushed a defeated prayer-in-schools bill, and vetoed a bill to ban transgender athletes from women’s school sports, only to see the legislature’s attempt to override her veto narrowly fail. After the U.S. Supreme Court overturned Roe v. Wade, South Dakota became one of the first states to enact trigger laws banning abortion, and in April 2024 Noem reversed her earlier support for a federal abortion ban in favor of state-level decisions.
Secretary of Homeland Security Era (2025-Present)
After resigning as governor of South Dakota, Noem was sworn in on 25 January 2025 by Supreme Court Justice Clarence Thomas as the eighth United States Secretary of Homeland Security, with Louisiana Governor Jeff Landry holding the Bible. In the early morning of 28 January 2025, she joined multiple federal agencies, including U.S. Immigration and Customs Enforcement, to lead a raid on undocumented immigrants in New York City, with her department posting video of the operation to X. She also deployed U.S. Coast Guard resources in support of search and rescue efforts following the January 2025 Potomac River mid-air collision.
Among her early actions in office, Noem rescinded an 18-month extension of Temporary Protected Status for roughly 600,000 Venezuelans who had fled the Maduro regime, and in March 2025 revoked legal protections for 532,000 people from Cuba, Haiti, Nicaragua, and Venezuela. She indicated the Department of Homeland Security would use Guantanamo Bay to detain migrants on a temporary basis and expressed comfort with the Department of Government Efficiency accessing sensitive data to identify waste, fraud, and abuse. In April 2025, The Washington Post reported that she and the acting Social Security commissioner had instructed the agency to falsely list more than 6,000 living immigrants in its database of dead people. The same month, her purse, containing her government access badge, passport, and thousands of dollars in cash, was stolen from a Washington, D.C. burger restaurant, raising questions about her security detail. In June 2025, ProPublica reported that she had failed to disclose past income from a nonprofit in her federal ethics filings upon joining the department.
Notable Events and Milestones
Noem’s career has been marked by several signature moments, from becoming the first woman elected governor of South Dakota to her leading role in one of the highest-profile immigration enforcement actions in recent memory. Her widely covered COVID-19 response, the controversial 2020 intervention in her daughter’s appraisal matter, the 2019 “Meth. We’re on It.” awareness campaign, and her 2025 confirmation as Secretary of Homeland Security have each shaped her public image. She has also gained attention for positions including opposition to same-sex marriage, vocal skepticism of climate change, and her description of the situation at the U.S. southern border as an “invasion.”
