Kristi Noem

Kristi Noem is an American public servant who served as the eighth United States Secretary of Homeland Security from 2025 to 2026. Prior to her cabinet appointment, she held elected office at both state and federal levels, including a tenure as governor of South Dakota and representation of that state's at‑large congressional district in the U.S. House of Representatives. Her service in the Department of Homeland Security was marked by significant policy debates over immigration enforcement and administrative conduct, culminating in her removal from the position in 2026 following congressional scrutiny.

Early life and career

Kristi Lynn Arnold Noem was born on November 30 1971 in Watertown, South Dakota. She grew up on a family ranch and farm near Hazel with her siblings. Her ancestry includes Norwegian roots, and she is a descendant of Ephraim Wilson, an American Revolutionary War veteran. In 1990, while attending Hamlin High School in Hayti, Noem was crowned the South Dakota Snow Queen.

Noem began higher education at Northern State University between 1990 and 1994 but did not complete her degree there. The death of her father in a grain‑bin accident in March 1994 prompted her to leave college early and take over operations of the family farm. A daughter, Kassidy, was born on April 21 1994, shortly after she assumed responsibility for the ranch. She expanded the family business by adding a hunting lodge and restaurant.

Afterward, Noem pursued further studies at the Watertown campus of Mount Marty College, South Dakota State University, and through online courses offered by the University of South Dakota. In 2012, while serving as a member of Congress, she earned a Bachelor of Arts degree in political science from South Dakota State University.

Noem’s entry into elected office began with her election to the South Dakota House of Representatives in 2006, representing the 6th district, which includes parts of Beadle, Clark, Codington, Hamlin, and Kingsbury counties. She served two terms from 2007 to 2011, during which she held the position of assistant majority leader in her second term. As a legislator, she was the prime sponsor of eleven bills that became law, notably reforms related to property taxes and gun rights. In 2009, she served as vice chair of the Agriculture Land Assessment Advisory Task Force.

In 2010, Noem ran for South Dakota’s at‑large seat in the U.S. House of Representatives. She won the Republican primary and defeated incumbent Democrat Stephanie Herseth Sandlin in the general election. Re-elected three times, she served in Congress from 2011 to 2019. Within her first year, she was elected by her freshman colleagues as liaison to the House Republican leadership, becoming one of the early women in that role. She also helped establish a political action committee and played an active part in fundraising efforts for fellow Republicans.

During her congressional tenure, Noem co-sponsored legislation aimed at restricting abortion, including a 2015 proposal to amend the Fourteenth Amendment to define human life as beginning at fertilization. She also supported measures to ban embryonic stem‑cell research. On environmental issues, she expressed skepticism toward mainstream scientific consensus on climate change.

In 2018, Noem was elected governor of South Dakota, becoming the state’s first female governor. Her gubernatorial campaign received endorsement from President Donald Trump. While in office, she attracted national attention for her opposition to statewide mask mandates during the COVID‑19 pandemic and her preference for voluntary public health measures.

Cabinet tenure

In 2025, Noem was appointed as United States Secretary of Homeland Security, succeeding the previous secretary. Her confirmation by the Senate marked the beginning of a cabinet-level role focused on national security, immigration enforcement, and emergency preparedness. The Department of Homeland Security oversees agencies such as Immigration and Customs Enforcement (ICE), U.S. Citizenship and Immigration Services, U.S. Coast Guard, and federal law‑enforcement coordination.

During her tenure, Noem’s approach to immigration policy drew significant controversy. She defended the actions of ICE agents involved in the killings of Renée Good and Alex Pretti in January 2026 before any formal investigation had taken place. The incident prompted calls from some lawmakers for her resignation or impeachment. In March 2026, she appeared before the Senate Committee on the Judiciary to address allegations concerning an inappropriate relationship with a subordinate named Corey Lewandowski, as well as claims of misuse of government funds for television advertising and private luxury jet travel. Additional accusations involved the improper use of U.S. Coast Guard assets and housing.

The testimony before the committee intensified criticism from members of Congress. Following the hearing, President Donald Trump announced his decision to remove Noem from her position at the Department of Homeland Security. Her departure in 2026 concluded a brief but highly scrutinized period as secretary.

Legacy

Noem’s service as Secretary of Homeland Security is remembered for its focus on stringent immigration enforcement and the controversies that surrounded her administrative conduct. The incidents involving ICE agents and subsequent congressional investigations highlighted tensions between executive directives and oversight mechanisms within federal law‑enforcement agencies. Her removal from office underscored the role of presidential authority in cabinet appointments and the impact of congressional scrutiny on executive leadership.

Beyond her cabinet tenure, Noem’s earlier political career—spanning state legislature, Congress, and the governorship—illustrates a trajectory marked by advocacy for limited federal spending, conservative positions on social issues such as abortion and gun rights, and skepticism toward mainstream environmental science. Her governance during the COVID‑19 pandemic emphasized voluntary public health measures over mandatory mandates.

Overall, Noem’s legacy in American politics reflects both her rapid ascent through elected office and the challenges inherent in balancing policy priorities with administrative accountability at the highest levels of federal government.
