Former Homeland Security Secretary Kristi Noem has filed for divorce from Bryon Noem, ending a marriage strained by months of public reports about his alleged secret life.
Newsweek reported that South Dakota court records show Kristi Noem officially filed for divorce on Monday, September 28, 2026, from her husband of more than three decades.
The filing lands after a year already marked by her removal from the Cabinet and a cascade of damaging claims about Bryon Noem’s private conduct. It also matches what her mother said months earlier: the marriage was headed for divorce.
Just The News reported that Noem cited irreconcilable differences, that the couple married in 1992, and that they have three adult children. The divorce comes roughly six months after she left the Department of Homeland Security.
The New York Post reported the petition was filed Monday in Hamlin County Court in South Dakota and also listed irreconcilable differences as the ground. Whether Bryon Noem will contest the case remains unclear.
Newsweek said it emailed attorneys for both sides on Tuesday seeking comment. No response was described in the available reporting.
Kristi and Bryon Noem married in Watertown, South Dakota, in 1992 after meeting in high school. He is a South Dakota native who built a career in banking and financial services before founding a crop insurance agency. Those basic biography points have long sat in plain public view. The past six months put a very different set of claims in the same frame.
On March 5, 2026, Kristi Noem was fired as Homeland Security secretary and assigned as special envoy for the Shield of the Americas. Less than a month later, on March 31, the Daily Mail published a report alleging Bryon Noem had led a double life.
That report claimed he exchanged large volumes of messages with women in so-called “bimbofication” online communities and included photos the outlet said showed him in leggings and false breasts. The claims were presented as allegations drawn from messages and images the paper said it reviewed. They were not treated in later coverage as courtroom findings.
Kristi Noem’s representatives answered at the time with a blunt statement of shock.
A representative told the New York Post:
"Ms. Noem is devastated. The family was blindsided by this, and they ask for privacy and prayers at the time.”
President Donald Trump also weighed in when the Daily Mail story broke.
Trump said:
"They confirmed it? Wow, well, I feel badly for the family if that's the case, that's too bad,"
The family’s ask for privacy did not slow the follow-on coverage. In April 2026, Bryon Noem gave his first known response, telling the New York Times he would speak at some later point.
Bryon Noem said:
“I will at some point. Today is not the day. I appreciate your heart,”
April brought additional women saying they had communicated with Bryon Noem. Webcam model Lydia Love said he had been her client. In the summer, further claims emerged, including from a Colorado sex worker who said he used a phone tied to his insurance business for paid calls. Again, these remained reported allegations, not adjudicated facts.
High-profile divorces rarely stay tidy once the filings start, a pattern familiar from other public cases, including when former Kentucky Gov. Matt Bevin faced divorce-related legal trouble that spilled into public view.
Separate attention also fixed on long-running rumors about Kristi Noem and Trump ally Corey Lewandowski. Those rumors were never established as fact in the reporting summarized here. Her mother rejected them outright.
In July 2026, Corinne Arnold, Kristi Noem’s mother, told the Daily Mail her daughter planned to divorce Bryon. Arnold also addressed the Lewandowski affair rumors and insisted her daughter “would never do that.”
That maternal confirmation lined up with later public signals that Kristi Noem intended to end the marriage, a stretch covered when Noem’s mother described the planned split after the cross-dressing scandal first dominated headlines.
By the time the September petition hit the docket, the direction had been telegraphed for months. Uncontested divorces in South Dakota can wrap up in as little as a month. Contested cases can run a year or longer. Which track this one takes is still unknown.
Public divorce drama is not limited to one party or ideology. Even months of divorce speculation around Barack and Michelle Obama showed how fast private strain becomes national noise once the press locks on.
Court records confirm the filing. They do not, in the reporting at hand, spell out a full docket number, a detailed property split, or whether service has been completed. Newsweek’s account did not reproduce the petition text itself.
The Daily Mail’s March claims about messages, photos, and online communities remain in the category of published allegations. So do the later statements from women who said they dealt with Bryon Noem. No criminal charges tied to those claims appear in this record.
Kristi Noem’s own earlier comment that she planned to divorce, her mother’s July statement, and the September 28 filing now form a straight line. The marriage that began in Watertown in 1992 is in court.
Readers tracking the personal fallout have also seen later images of Noem and Corey Lewandowski together at a Minnesota lake after the divorce news, another reminder that the private and political circles around her remain under a hard spotlight.
Large-money divorce fights elsewhere, including a decade-long battle that produced a $645 million order against a South Korean AI billionaire, show how bitter and slow these cases can turn when the parties dig in. Nothing in the South Dakota coverage yet puts the Noems on that track. Nothing rules it out either.
For a former Cabinet secretary, the sequence is stark: removal from DHS in March, a humiliating round of claims about her husband’s conduct, a mother’s public confirmation of divorce plans, and now a signed petition. The filing does not settle every rumor. It does settle the legal status of the marriage she entered in 1992.
Families get broken in public long before a clerk stamps the paperwork. The decent response is to let the court process run and spare the children the rest of the circus.
