Noem, who was tasked with leading Donald Trump’s immigration crackdown from January 2025 to March 2026 and previously served as South Dakota’s governor, is seeking a divorce from Bryon Noem in their home state. The two married in May 1992 and have three children.

The filing, submitted to the court in April but posted online on Monday, comes after questions arose earlier this year about the nature of Kristi Noem’s relationship with a top adviser. The complaint, filed in Hamlin County, South Dakota, notes “irreconcilable differences” as grounds for the divorce.
