Kristi Noem Biography – Age, Height, Family, Net Worth, and Political Journey — Former South Dakota Governor and DHS Secretary

Kristi Noem has emerged as one of the most polarizing figures in American politics, transforming from a South Dakota rancher to the first female governor of her state, and finally to Secretary of Homeland Security under Donald Trump. Her journey from rural Hamlin County to leading one of the federal government’s largest departments has been marked by viral moments, ethical controversies, and persistent questions about her judgment and personal conduct that culminated in her dramatic firing in March 2026.

Quick Facts

Early Life & Education

Kristi Lynn Arnold was born on November 30, 1971, in Watertown, South Dakota, and grew up on her family’s ranch and farm in rural Hamlin County, in east-central South Dakota . She was one of four children born to Ron and Corinne Arnold, learning the values of hard work, agriculture, and rural self-reliance from an early age.

In 1990, during her senior year at Hamlin High School, Arnold was crowned Snow Queen at the South Dakota Snow Queen Festival . She later reflected that this experience provided her with “the first opportunity to sit in an interview, to speak in public”—skills that would prove invaluable in her political career . As a teenager, she also competed in rodeo queen contests, developing the pageant presence that would later characterize her political style .

Noem initially attended Northern State University in Aberdeen, South Dakota, but her academic path was dramatically altered by family tragedy. In 1994, her father Ron was killed in a farming accident . With her elder siblings having left the state and her younger brother still in high school, Noem dropped out of college to return home and help her husband Bryon run the family farm and ranch .

This decision—prioritizing family obligation over personal advancement—became a cornerstone of her political narrative. While managing the growing agricultural operation and raising her children, Noem continued her education through distance learning and night classes. In 2011, while serving in the U.S. House of Representatives, she completed her Bachelor of Arts in Political Science from South Dakota State University .

Noem is an avid hunter and built a hunting lodge on her family’s property, establishing what would become a diversified agricultural and hospitality business .

Career Journey

South Dakota State Legislature (2006-2010)

Noem entered electoral politics in 2006 when she was elected to the South Dakota House of Representatives from the 6th district, taking office in January 2007 . During her second term, she became Assistant Majority Leader, demonstrating rapid leadership advancement .

In the state legislature, Noem was a leader in establishing a productivity-based assessment system for agricultural property valuations—policy expertise that would inform her later work on agricultural issues in Congress . Her state legislative service established her reputation as a conservative voice for rural interests and limited government.

U.S. House of Representatives (2011-2019)

In 2010, Noem ran for South Dakota’s at-large seat in the U.S. House of Representatives following the retirement of Democratic incumbent Stephanie Herseth Sandlin . She won a competitive three-way Republican primary and defeated Herseth Sandlin in the general election, becoming the first woman to represent South Dakota in Congress .

Committee Assignments and Leadership:

• House Ways and Means Committee (first South Dakotan to serve on this powerful committee)
• Final negotiating team for President Trump’s 2017 tax cut legislation
• Co-liaison between freshman Republican members and House leadership

Legislative Priorities:
Noem established herself as a reliably conservative vote, backing spending cuts and seeking to limit the Environmental Protection Agency’s power . She led on agricultural issues and helped write two farm bills, leveraging her farming background to become a voice for rural America .

In August 2013, conservative Newsmax magazine named Noem among the “25 most influential women in the GOP” . She was reelected three times to the House, building a national profile within Republican circles.

Governor of South Dakota (2019-2025)

Historic Election:
In 2018, Noem ran for Governor of South Dakota to succeed term-limited Republican Dennis Daugaard. She won the Republican nomination in a contentious and costly primary, then defeated Democratic state Senator Billie Sutton in the general election with 51% of the vote . When sworn into office on January 5, 2019, she became the first woman to serve as South Dakota’s governor .

First Term (2019-2023):

• COVID-19 Response: Noem gained national attention for refusing to close businesses or impose mask mandates during the pandemic. South Dakota had the third-highest COVID-19 death rate in 2020 but was one of only two states where unemployment dropped that year . She opposed President Biden’s vaccine mandate and signed executive orders reinforcing medical and religious exemptions .
• Social Media Presence: Noem developed a viral social media persona, posting a video of herself shooting a pheasant to demonstrate “how we do social-distancing in [South Dakota]” that garnered national attention . The Washington Post noted she seemed to take “a great deal of inspiration from Trump,” from frequent social media postings to Fox News appearances and “her penchant for jumping into controversy on social issues” .
• Real Estate License Controversy: In 2020, after her daughter Kassidy’s application for a real-estate appraiser license was recommended for denial, Noem called a meeting with the director of the licensing agency. The director later said she felt “intimidated,” and Noem’s daughter received her license four months later. The director was allegedly pressured to retire later that year .
• Transgender Healthcare Settlement: In 2023, Noem’s administration was sued by a nonprofit providing services to transgender South Dakotans after the state ended a contract funding a community health worker. In 2024, South Dakota agreed to a settlement requiring an apology and $300,000 payment to the organization .

Second Term (2023-2025):
Noem was reelected in 2022 with the largest vote total in South Dakota history, raising over $15 million and breaking state records for a gubernatorial candidate . Abortion became a major campaign issue following the overturning of Roe v. Wade, with Noem supporting South Dakota’s trigger law banning all abortions except when the pregnant person’s life is in danger .

Tribal Relations Breakdown:
By 2024, Noem found herself banned from approximately 20% of South Dakota after all Native American tribes in the state barred her from their reservations. The animosity escalated when she began accusing tribal leaders of involvement with drug cartels .

U.S. Secretary of Homeland Security (2025-2026)

Nomination and Confirmation:
Following Trump’s 2024 election victory, he nominated Noem for Secretary of Homeland Security. The Senate confirmed her on January 25, 2025, by a vote of 59-34, making her the first South Dakotan to lead the department . She resigned as governor the same day and was sworn in by Supreme Court Justice Clarence Thomas .

Department Leadership:
As Secretary, Noem led one of the federal government’s largest departments with 260,000 employees and a budget exceeding $100 billion . She became the public face of the Trump administration’s immigration crackdown, personally appearing at ICE raids wearing protective gear .

Major Incidents and Controversies:

• Alex Padilla Incident (June 2025): During a press conference about National Guard deployment to Los Angeles, Noem’s protective detail forced California Senator Alex Padilla to the ground and briefly handcuffed him when he tried to ask her a question. Noem later claimed she did not know who Padilla was .
• Renee Good Killing (January 2026): Following the killing of U.S. citizen Renee Nicole Good by an ICE agent in Minneapolis, Noem immediately labeled Good a “domestic terrorist” who “weaponize[d]” her car, claiming the agent fired “defensive shots.” Video evidence contradicted this narrative, sparking protests .
• Alex Pretti Killing (February 2026): Less than three weeks later, federal agents shot and killed another U.S. citizen, Alex Pretti, in Minneapolis. Noem again made statements contradicted by bystander video, claiming Pretti was “brandishing” a weapon and “attacked” officers .
• $220 Million Ad Campaign Controversy: Noem authorized a $220 million advertising campaign featuring herself prominently, telling Congress that Trump had approved it. When questioned by Reuters, Trump stated he “never knew anything about it” and was reportedly “mad as a murder hornet” over her testimony .

Firing and Reassignment (March 2026)

On March 5, 2026, Trump fired Noem as Secretary of Homeland Security in his first Cabinet shakeup of his second term . The firing came after her controversial congressional testimony about the ad campaign and amid persistent questions about her relationship with Corey Lewandowski.

Within minutes of her firing, Trump appointed Noem as Special Envoy for the Shield of the Americas, a new position focused on hemispheric security cooperation . In her first remarks after the firing, Noem stated she was “grateful for the opportunity to serve” and looked forward to her new role .

Personal Life

Kristi Noem married Bryon Noem in 1992, shortly after graduating from high school . Bryon earned a finance degree from Northern State University and runs an insurance agency in Bryant, South Dakota . The couple has three children: Kassidy, Kennedy, and Booker .

Noem frequently describes raising her children as her “greatest accomplishment” and emphasizes her identity as a “wife, mother, and lifelong rancher, farmer and small business owner” . The family maintains their ranch in Castlewood, South Dakota, where they continue agricultural operations alongside the hunting lodge business.

Bryon Noem has largely remained out of the political spotlight, though he attended his wife’s March 2026 congressional testimony and sat behind her during the hearing where she was grilled about her alleged affair with Corey Lewandowski . He left the hearing early, before the most pointed questions about the alleged relationship were asked .

Controversies and Scandals

The Dog and Goat Shooting (2024)

In April 2024, The Guardian published excerpts from Noem’s forthcoming memoir No Going Back that sparked bipartisan outrage. Noem described shooting her 14-month-old dog Cricket in a gravel pit because the dog was “untrainable,” “dangerous,” and “less than worthless … as a hunting dog” .

The controversy significantly damaged Noem’s reputation and was widely cited as a reason she was not selected as Trump’s 2024 vice presidential running mate .

The Corey Lewandowski Affair Allegations (2025-2026)

Since early 2025, Noem has been at the center of persistent rumors about an affair with Corey Lewandowski, her senior advisor at DHS—described as “the worst-kept secret in Washington, D.C.” .

Evidence and Reports:

• Noem and Lewandowski frequently travel together on government jets with a private cabin
• President Trump has allegedly asked about their relationship and privately teased them
• A Trump transition team member told NBC News in January 2025: “Oh yeah, they’re still fucking”
• DHS officials stated they “do little to hide their relationship”
• Lewandowski has been seen entering and exiting Noem’s apartment

Congressional Testimony (March 4, 2026):
During a House Judiciary Committee hearing, Noem was directly asked about the alleged affair by Representative Sydney Kamlager-Dove (D-Calif.): “Secretary Noem, at any time during your tenure as Director of the Department of Homeland Security, have you had sexual relations with Corey Lewandowski?”

Noem refused to answer directly, responding: “I am shocked that we’re going down and peddling tabloid garbage in this committee today” . When pressed by Representative Jared Moskowitz (D-Fla.) to “say the word ‘no’ into the record,” Noem again deflected, stating the allegations were “insane” and attacking the “socialist liberal left” .

“This is what you do—the socialist liberal left—is you go off and you attack conservative women,” Noem fired back. “You say that we’re either stupid, or we’re sl-ts … I’ll tell you, sir, I’m neither” .

Despite multiple opportunities, Noem never directly denied the affair under oath.

The “Blanket” Incident (May 2025):
Reports emerged that Lewandowski entered the cockpit of a Coast Guard jet while in flight after Noem’s favorite blanket was left behind on another aircraft . He allegedly attempted to fire the pilot for refusing to turn back. The pilot was subsequently promoted to a DHS senior adviser . Noem denied this report during her congressional testimony .

Tribal Ban from Reservations (2024)

By early 2024, all Native American tribes in South Dakota had banned Noem from their reservations, covering approximately 20% of the state . The ban followed years of clashes with tribal leaders and escalated dramatically when Noem accused tribal leaders of involvement with drug cartels .

ICE Agent Killings of U.S. Citizens (2026)

Noem faced intense criticism for her responses to two killings of U.S. citizens by ICE agents in Minneapolis:

• Renee Good (January 2026): Noem immediately labeled Good a “domestic terrorist” who “weaponize[d]” her car; video contradicted her account
• Alex Pretti (February 2026): Noem claimed Pretti was “brandishing” a weapon and “attacked” officers; bystander video again contradicted her narrative

Both incidents sparked protests and raised questions about ICE conduct and Noem’s truthfulness.

$220 Million Self-Promotional Ad Campaign (2026)

Noem authorized a $220 million DHS advertising campaign featuring herself prominently, telling Congress that Trump had pre-approved the expenditure . Trump subsequently denied knowledge of the campaign, reportedly becoming “mad as a murder hornet” over her testimony . This discrepancy contributed to her firing days later.
