The woman reportedly told the Wisconsin Department of Justice about the incident on Friday. "He knew everything that I wanted to hear as a domestic violence victim," she said. "I needed to be taken care of ... protected."
Kratz has been accused of sending sexually suggestive text messages to multiple women, and even allegedly inviting a date to an autopsy.
The Wisconsin Office of Lawyer Regulation reopened its investigation into Kratz last week.
He is scheduled to appear in court today.
Kratz has refused to step down, but did go on medical leave last week. His attorney told the Appleton Post Crescent last week that despite what he called the "scratching-your-head texts," Kratz hopes to eventually return to his post.
