Sen. Joni Ernst, R-Iowa, said Wednesday she was raped in college in an interview that comes after allegations of a violent relationship with her ex-husband came to light.

Ernst, 48, told Bloomberg that she was sexually assaulted one night by someone with whom she was in a relationship at his home while she was an Iowa State University student. Though she said she didn’t report her assault to police, she later volunteered at her campus’ sexual assault counseling center where she sought help after the incident.
