ST. PAUL — Minnesota Democratic Rep. Keith Ellison said Wednesday he’s requesting a House Ethics Committee investigation into the allegation of physical abuse from an ex-girlfriend that is clouding his bid for attorney general and complicating Democrats’ push to investigate allegations against Supreme Court nominee Brett Kavanaugh.

Karen Monahan said last month Ellison dragged her off a bed by her feet while screaming obscenities at her. She claimed to have video footage of the 2016 incident but has declined to release it.
