They met the way a lot of people in rural South Dakota meet. Two farm kids from Hamlin County, attending the same high school two years apart, connected through her older brother. They married in 1992, when she was 20. Over the next three decades, they raised three children on a family ranch, buried her father after a farming accident, built an insurance business, and then found themselves in the governor’s residence in Pierre and eventually in the orbit of Washington, D.C.
On Monday, September 28, 2026, Kristi Noem filed for divorce from Bryon Noem in Hamlin County, South Dakota, citing irreconcilable differences. The filing ended a marriage of more than 34 years.
This is a timeline of that marriage: how it began, how it intersected with one of the more rapid political rises in recent South Dakota history, and the sequence of events in 2026 that preceded the filing. The reporting here is drawn from court documents and mainstream coverage, and where allegations are involved, they are identified as allegations.
How Kristi and Bryon Noem First Met
Both Kristi and Bryon grew up on farms in Hamlin County, South Dakota, a rural county in the eastern part of the state.
They attended the same high school, where Bryon was two years older. The age gap meant they were not classmates, but they knew each other because Bryon was friends with Kristi’s older brother. That connection through family is how the relationship began.
Kristi was born Kristi Lynn Arnold on November 30, 1971, in Watertown, South Dakota, to Corinne and Ron Arnold. She is 54 years old.
Bryon grew up in Hamlin County and went on to graduate from Northern State University with a degree in business finance. After college, he coached before moving into other work. He later spent roughly 10 years working on the Arnold family farm, the operation Kristi’s family ran.
The 1992 Marriage and Early Years

The early years of the marriage were shaped by farm life and, before long, by tragedy. On March 10, 1994, Kristi’s father, Ronald Arnold, died in an accident on the family farm. She was 22. The loss pulled her back into the family operation and interrupted her education. She would later take classes at the Watertown campus of what is now South Dakota State University and complete her degree years afterward.
Bryon’s decade of work on the Arnold farm overlapped with this period. He eventually moved into the insurance business, where he has worked as an agent for many years and built his own professional identity separate from the farm.
The couple had three children together: daughters Kassidy and Kennedy, and son Booker. Kennedy was born in 1997 in Watertown and raised on the family ranch in Castlewood. The Noems have since become grandparents.
Bryon has walked both of his daughters down the aisle at their weddings.

The Political Rise and the First Gentleman Years
Kristi Noem political career began in 2006, when she won a seat in the South Dakota House of Representatives as a Republican. She served four years, from 2007 to 2010.
In 2010, she ran for the United States House of Representatives and won, becoming South Dakota’s at-large member of Congress. She held that seat until 2019.
In 2018, Noem was elected governor of South Dakota, becoming the first woman to hold the office in the state’s history. That election made Bryon Noem the state’s inaugural first gentleman, a role that had never existed before because every previous South Dakota governor had been a man.
As first gentleman, Bryon maintained his insurance work while taking on public duties. He launched an initiative focused on South Dakota’s small businesses and appeared alongside his wife at official functions. He was a regular presence at her public appearances, including congressional hearings after she moved to federal service.
Kristi Noem was re-elected governor in 2022. In January 2025, she was confirmed as the eighth United States Secretary of Homeland Security under President Donald Trump, and the family’s public profile expanded to the national stage.
2026: The Year That Changed Everything
The final year of the marriage was, by any measure, extraordinarily turbulent, involving both professional upheaval for Kristi Noem and intense public scrutiny of Bryon Noem.

In March 2026, during a House Judiciary Committee hearing, Kristi Noem was questioned about allegations that she had a relationship with Corey Lewandowski, an aide to President Trump. She also faced questions regarding the use of government funds. She was removed from her position as Homeland Security Secretary on March 5, 2026, and Markwayne Mullin was subsequently sworn in as her successor. On March 24, she was appointed special envoy for the Shield of the Americas, the role she currently holds.
Later that month, on March 31, the Daily Mail published a report alleging that Bryon Noem maintained a private online presence in which he communicated with adult performers, accompanied by photographs that appeared to show him wearing women’s clothing. Mainstream outlets including NBC News and Fox News subsequently reported on the story. The specific content of those reports has been widely circulated, but the graphic details are not necessary to understand the timeline and are not reproduced here.
A spokesperson for Kristi Noem said at the time that she was “devastated” by the discovery. Bryon Noem’s first known public response came in April 2026, when he told The New York Times that he would eventually grant an interview about the allegations. As of the divorce filing, an attorney for Bryon Noem had not responded to requests for comment from multiple outlets.
In July 2026, Kristi Noem’s mother, Corinne Arnold, told the Daily Mail that her daughter intended to divorce Bryon.

The filing cites irreconcilable differences, the standard no-fault ground used in the vast majority of American divorce cases. It does not allege misconduct as a legal basis for the dissolution.
One notable detail emerged from the court documents: Kristi Noem’s attorneys signed the divorce paperwork on April 6, 2026, roughly six days after the initial Daily Mail report and nearly six months before the documents were actually filed with the court. The reason for that gap has not been publicly explained.
It is not currently clear whether Bryon Noem is contesting the divorce. No public statement has been issued by him regarding the filing.

What Happens Next
South Dakota divorce proceedings involving irreconcilable differences typically move through a standard process, though timelines vary considerably depending on whether the filing is contested and how complex the marital estate is.
Because Bryon Noem’s position on the filing is not yet known publicly, it is not possible to predict whether the case will resolve quickly through agreement or extend through contested proceedings. The Noems’ children are all adults, which removes custody from the equation entirely.
Kristi Noem continues to serve as special envoy for the Shield of the Americas. Whether the divorce affects her political future is a matter of speculation rather than reporting, and this article does not attempt to forecast it.
For a couple who met as teenagers in a rural South Dakota county and spent more than three decades together, the ending has played out with a degree of public exposure that few marriages endure. Both remain public figures, and both have, so far, said very little.
