Kristi Noem filed for divorce from her husband, Bryon Noem, after 34 years of marriage, according to court records in their home state of South Dakota.

The former Department of Homeland Security (DHS) secretary filed the divorce paperwork on Monday, Sept. 28, in South Dakota’s Hamlin County, where the high school sweethearts resided during her tenure as the state’s governor and when she later served in President Donald Trump’s Cabinet.

The divorce comes months after Kristi, 54, was pushed out of her position atop DHS, and reports that Bryon, 56, participated in online fetish forums.

Kristi cited irreconcilable differences as the reason for the divorce, Dakota News Now reported.
