After more than three decades of marriage, Kristi Noem and her husband, Bryon Noem, are divorcing.
The former South Dakota governor and former U.S. Homeland Security secretary has filed to dissolve the marriage she entered in 1992, citing “irreconcilable differences.” The case is in Hamlin County, South Dakota. ABC News
News of the filing emerged at the end of September 2026, bringing months of public speculation about the couple’s marriage to a definitive legal turning point.
And the timing has created some confusion.
Although several initial reports said Noem filed on September 28, records reviewed by USA Today indicate the case was originally filed on April 6, 2026, but wasn’t posted publicly online until September 28. Currently
For a couple who had been together since their youth, it marks the end of an extraordinarily long chapter.
They were high-school sweethearts
Kristi and Bryon knew each other long before politics made the Noem name nationally recognizable.
They grew up in South Dakota and met during their school years. They eventually married on May 23, 1992, when they were both young adults. Currently
Together they built a family and raised three children — Kassidy, Kennedy and Booker — and eventually became grandparents. People.com
Bryon generally remained far less visible than his increasingly famous wife.
While Kristi built a political career that would take her from the South Dakota legislature to Congress, the governor’s mansion and eventually Washington, Bryon maintained a comparatively private life. He worked on the family farm and later established an insurance business. People.com
For years, they continued appearing together at public events.
But by 2026, their marriage had entered a dramatically different period.
The filing says their differences can no longer be resolved

The couple’s children are adults, meaning the proceedings won’t involve the kind of child-custody arrangements often central to divorces involving younger families.

Her attorney, Michael K. Sabers, subsequently confirmed the divorce and said Noem would leave further discussion to the legal proceedings. People.com
She has not publicly offered a detailed explanation for the breakup.
But trouble in the marriage had already become public
Months before the divorce became public record, the Noems’ relationship was receiving unwanted attention.
In March 2026, reports emerged concerning Bryon’s alleged participation in adult online fetish communities. Images published at the time appeared to show him cross-dressing and wearing exaggerated prosthetics. Representatives for Kristi said she and her family had been blindsided and devastated by the revelations. People.com
Bryon’s alleged private activities quickly became tabloid material.
But the divorce documents themselves do not establish those reports as the legal cause of the marriage ending. They cite irreconcilable differences. Currently
That distinction is important because the couple’s relationship had also faced other public speculation.
Kristi faced rumors about her own marriage as well
For years, reports had alleged that Noem had a romantic relationship with political strategist Corey Lewandowski.
Both have denied allegations of an affair. People.com
Those claims resurfaced during Noem’s turbulent final months in Washington, but publicly available divorce records do not establish an affair as a reason for the split.
By spring 2026, however, the marriage itself appears to have reached its conclusion.
And according to Kristi’s mother, the family already knew it.
Her mother revealed the split months before the paperwork became public
In July, Kristi’s mother, Corinne Arnold, discussed the marriage publicly.
Arnold said she had directly asked her daughter whether there was any possibility that she and Bryon would reconcile.
According to Arnold, Kristi told her they were going to divorce. Currently
At the time, it was significant confirmation that the separation wasn’t merely an internet rumor.
What the public didn’t yet know was that divorce proceedings had apparently already begun.
If the April 6 filing date reported from the court record is correct, Kristi had taken the legal step months before her mother’s comments became public. Currently
Then came a cryptic public message
As news of the divorce began spreading, attention inevitably turned toward Noem’s recent social-media activity.
Brief messages that might ordinarily have attracted little attention suddenly became subject to interpretation because of what was happening privately.
But there is no verified public evidence establishing that a cryptic three-word post was specifically intended as a message about Bryon or their divorce.
Without Noem explaining its meaning herself, connecting such a post directly to the breakup would be speculation.
What is documented is considerably clearer: her marriage of more than 34 years is ending.
Their wedding photographs now belong to another era
The contrast is particularly striking when looking at RARE PHOTOS of Kristi and Bryon from their early years together.
Their wedding photographs show an almost unrecognizable version of the couple.
Kristi was a young blonde bride.
Bryon stood beside her in a tuxedo.
Neither had any idea that their lives would eventually include congressional campaigns, a South Dakota governorship, the Department of Homeland Security and intense national scrutiny.
They built much of their adult lives together.
When Kristi’s father died unexpectedly in a farming accident, she returned to help operate the family’s property. Bryon was part of those formative years, long before her political career reached Washington. People.com
Their three children grew up as that career expanded.
Eventually, Kristi became South Dakota’s first female governor.
Bryon had his own role as South Dakota’s “First Gentleman”
When Kristi became governor in 2019, Bryon became the state’s First Gentleman.
He used the position to promote small communities throughout South Dakota while generally avoiding the national political spotlight surrounding his wife.
That arrangement lasted until Kristi left the governorship to join President Donald Trump’s second administration.
She became secretary of Homeland Security in 2025.
Her tenure was highly contentious and ended in March 2026 when Trump removed her from the position. ABC News
Only weeks later, according to the court-record timeline reported by USA Today, the divorce case was filed. Currently
The proximity of those events does not establish that they were causally connected.
But it made 2026 an unusually turbulent year in both Noem’s professional and private life.
Thirty-four years can’t be reduced to the scandal surrounding their final months
The recent headlines are dramatic.
But the RARE PHOTOS spanning Kristi and Bryon’s decades together tell a much longer story.
There was the young wedding photograph.
The years raising three children.
Life on the family farm.
Her earliest campaigns.
Her years in Congress.
The governorship.
Their children becoming adults.
Grandchildren arriving.
And finally Washington.
By the time the marriage ended, the couple had spent virtually their entire adult lives connected to one another.
That makes the simple language appearing in the divorce filing — “irreconcilable differences” — particularly stark. Washington Examiner
For now, Kristi isn’t saying much more
Despite the enormous attention surrounding the filing, Noem’s official response has been restrained.
Her attorney confirmed that she had filed for dissolution of the marriage and said she had confidence in South Dakota’s judicial system. Further comments, he indicated, would be reserved for the legal process. People.com
Bryon has not publicly offered a detailed account of the breakup either.
That leaves many of the personal questions unanswered.
Exactly when did the marriage become irreparable?
What happened privately before the filing?
And what will their relationship look like after spending more than three decades together?
The court documents provide the legal fact, not the intimate story behind it.
What they establish is that the marriage that began in South Dakota in May 1992 has reached its final chapter.
After 34 years, three children, grandchildren and an extraordinary journey from farm life to the national political stage, Kristi Noem has formally asked a court to end her marriage to Bryon Noem. Currently
