Kristi Noem has filed for divorce from her husband, Bryon Noem, citing “irreconcilable differences” in court documents. The filing comes after reports about Bryon’s online exchanges with pornography performers and cross-dressing, and follows earlier reports that the couple planned to separate.

The documents were submitted in April and appeared on Hamlin County’s online court service on Monday. The couple married in 1992; Bryon declined to comment when asked about the proceedings by a South Dakota news outlet. The article also refers to longstanding reports of an alleged affair involving Noem and adviser Corey Lewandowski.
