A judge who serves nearly a dozen counties in eastern Iowa faces a charge of domestic assault.

Authorities arrested 49-year-old Stephanie Rattenborg after an alleged assault at her home in Manchester on Friday.

She is an associate judge for Iowa's First Judicial District, which includes Dubuque, Black Hawk and Delaware Counties.

The Iowa Attorney General's office told KCRG-TV9 that it is prosecuting the case at the request of the Delaware County Attorney's office.

The Iowa Judicial Branch said Rattenborg will continue to work, unless the Judicial Qualifications Commission suspends her.
