After days of silence, the Democratic National Committee weighed in Tuesday on the accusations of domestic violence against its deputy chairman, Keith Ellison.

Ellison’s former girlfriend, prominent environmental activist Karen Monahan, and her son last week accused the Minnesota representative in several passionate social-media posts of beating and verbally abusing her while they were in a relationship a few years ago.

“I was using my moms computer trying to download something and I clicked on a file, I found over 100 text and twitters messages and video almost 2 min long that showed Keith Ellison dragging my mama off the bed by her feet, screaming and calling her a ‘fu**ing bi*ch’ and telling her to get the f**k out of his house,” Monahan’s son, Austin, wrote in a Facebook post.

Monahan backed up those claims on Twitter, telling Ellison, “You know you did that to me.”

Ellison has denied the allegations.

“Karen and I were in a long-term relationship which ended in 2016, and I still care deeply for her well-being,” the Democratic National Committee deputy chairman said Sunday in a statement. “This video does not exist because I never behaved in this way, and any characterization otherwise is false.”

The accusations came out over the weekend, but the DNC chose to wait to make a statement until late Tuesday, after voting for Ellison in the Minnesota primary was well underway. The congressman won his bid for the Democratic nomination for attorney general despite the accusations.

“These allegations recently came to light and we are reviewing them. All allegations of domestic abuse are disturbing and should be taken seriously,” read a DNC statement to NPR, published shortly before polls closed in Minnesota.

“The party has no choice but to suspend him at a minimum until they figure out what’s going on,” former DNC communications director Luis Miranda told NPR. “Frankly, it would be malpractice not to. We’ve made it clear we’re going to take these accusations seriously, at a minimum. We set too high a standard not to take this seriously.”

“We watched her so called political friends stand by say or do nothing,” Monahan’s son wrote on Saturday. “People had an idea what happened and never reached out to my mom. The same people who are posting about social justice are ready to smear my mom, protect a person who abused her and broke the law.”
