Former Homeland Security Secretary Kristi Noem has filed for divorce from husband Bryon Noem after more than 34 years of marriage, citing irreconcilable differences in a South Dakota court.
ABC News reported that the complaint was signed by her lawyer in April and lodged Monday with the Hamlin County court, putting a formal endgame on a union that began when the pair were high school sweethearts.
The filing lists irreconcilable differences as the ground. Under South Dakota law, the action also places both parties under a temporary restraining order while the case proceeds.
Court records described in earlier coverage track the same core request: dissolve the marriage after roughly three and a half decades together.
Michael K. Sabers, the attorney speaking for Kristi Noem, kept the public statement short and pointed to the courtroom.
"Kristi Noem has filed for the dissolution of her marriage to Bryon Noem. She has great faith in the South Dakota judicial system and will reserve any further comments for the legal process."
Tim Bottum, the lawyer for Bryon Noem, told ABC News his client is “saddened” the marriage is ending. Bottum added a conditional note about any fight still to come.
"If court proceedings become necessary, Bryon will welcome the opportunity to truthfully share his perspective,"
The Washington Examiner likewise reported the split after 34 years, with irreconcilable differences named in the papers.
Just The News placed the marriage back to 1992 and noted the couple has three adult children. Grandchildren are part of the family picture as well.
Bryon Noem had long been a familiar presence beside his wife. File images from her Homeland Security tenure show him listening through Senate testimony in Washington in May 2025 and standing with her after a July 2025 news conference in Nashville.
That public solidarity is now a court matter in a rural South Dakota county, far from the hearing rooms where she once defended department policy.
The legal step follows a March storm of tabloid coverage. The Daily Mail published photos that appeared to show Bryon Noem in women’s clothing and large fake breasts, and it alleged he had exchanged messages with women online and made payments to some of them.
The New York Post reported that a representative for Kristi Noem said at the time she was “devastated” by the revelation and that “the family was blindsided by this, and they ask for privacy and prayers at the time.”
Those claims were never framed in the available court description as formal findings. The divorce papers, as described, stick to irreconcilable differences rather than a public bill of particulars.
Months of fallout inside the marriage had already become part of the political backdrop before the clerk stamped the complaint.
Breitbart tied the filing to the aftermath of that March 31 Daily Mail report and reported the couple’s wedding date as May 23, 1992. It also carried a curt line from Bryon Noem: “I can’t comment right now.”
Years earlier, in 2021, Kristi Noem had answered a different round of personal rumors in blunt terms, saying she loved Bryon and was proud of the “God-fearing family” they had raised. The new case leaves those older defenses in the past tense.
The divorce arrives months after a hard break in her federal role. President Donald Trump fired Noem as Homeland Security secretary in March and replaced her with Sen. Markwayne Mullin.
Trump then named her special envoy to the “Shield of Americas,” a coalition linking the United States with governments in Latin America. The title kept her in the orbit of border and regional security work after the Cabinet exit.
During her DHS tenure, congressional inquiries also swirled around her relationship with chief adviser Corey Lewandowski. Noem and Lewandowski denied anything romantic. The denial did not stop the speculation that followed her through hearings and headlines.
Readers tracking the pair’s later public movements saw fresh attention on Noem and Lewandowski after the divorce news, a reminder that personal filings rarely end the political chatter around them.
Lewandowski’s own maneuvering in Trump world, including talk of future primary fights in South Dakota, has kept both names in influence stories even as Noem’s household drama moved into probate-style paperwork.
Family reaction has been part of the wider narrative as well, including reports on relatives describing plans to end the marriage after the tabloid shock.
Hamlin County now owns the procedural clock. The temporary restraining order is automatic under state divorce rules, not a separate finding of abuse or misconduct. Irreconcilable differences is the clean statutory box South Dakota couples use when they are done arguing the reasons in public.
No full docket narrative has been laid out beyond that ground, the April signature, the Monday filing, and the lawyers’ brief statements. Who sought what asset, what parenting or grandparenting terms matter, and whether either side pushes past a quiet settlement remain open.
For a figure who governed South Dakota, ran a federal security department, and still holds a presidential envoy brief, the venue is deliberately local. The national audience gets the fact of the split. The county court gets the file.
Bryon Noem’s attorney left the door cracked on a fuller account if motions force one. Kristi Noem’s attorney shut the microphone and pointed at the judicial process. That is the posture both camps are holding while the clerk’s stamp is still fresh.
Private failure is not a policy platform. A long marriage is ending in a South Dakota courthouse, on the record, without a press-tour monologue, and the country can let the judge handle it.
