Rep. Keith Ellison (D-Minn.) said Friday that he can’t be sure there won’t be additional abuse allegations brought against him, more than a month after his former girlfriend publicly accused him of domestic abuse.

Ellison, the deputy chairman of the Democratic National Committee, has denied Karen Monahan’s allegations accusing him of repeated verbal abuse, and at least one instance of physical abuse, during their yearslong relationship.

Monahan wasn’t the first woman to accuse Ellison of abusive behavior. In 2006, Amy Alexander wrote a piece in The Wright County Republican claiming he “berated” and “pushed” her during their on-and-off relationship between 1993 and 2005. Ellison has denied Alexander’s allegations as well.

During a televised debate Friday against his Republican opponent in the Minnesota attorney general’s race, Ellison hesitated when asked about the potential for future abuse allegations against him.

“Look, you know, in this political environment, you know, I don’t know what somebody might cook up,” Ellison said. “But I can tell you that there is absolutely nobody that I’m aware of ... who’s threatening or suggesting or has ever made a prior accusation.”

Two days before the Aug. 12 Democratic primary for Minnesota attorney general, Monahan released a lengthy statement describing the alleged abuse. She accused Ellison of repeatedly calling her names, manipulating her and cheating on her beginning in 2014. In one instance, she said he dragged her off a bed by her legs and told her to “get the fuck out” of his house.

Ellison said Friday that there was an ongoing, independent investigation into the allegations, but wasn’t sure when it would be completed when asked if its findings would be released before the midterm elections in November.

Doug Wardlow, Ellison’s Republican challenger in the Minnesota attorney general’s race, attacked the credibility of any such investigation.

“It’s not an independent investigation,” Wardlow said. “It’s independent by your friends and fellow party members. That’s not an independent investigation.”

Ellison easily defeated his Democratic challengers last month, despite the abuse allegations.
