The Democratic National Committee said it is looking into charges of domestic abuse by Rep. Keith Ellison, who serves as deputy chairman of the organization.

“These allegations recently came to light and we are reviewing them,” the committee said in a statement to NPR. “All allegations of domestic abuse are disturbing and should be taken seriously.”

The allegations came to light shortly before Ellison won the Democratic Farmer-Labor nomination for attorney general of Minnesota on Tuesday.

Ellison has denied the allegations made by the son of his ex-girlfriend Karen Monahan that he abused her.

Monahan’s son Austin Aslim said in a Facebook post Sunday that he found a video on his mother’s computer showing Ellison “dragging my mama off the bed by her feet, screaming and calling her a ‘f—ing bitch’ and telling her to get the f— out of his house.”

Monahan tweeted a statement confirming her son’s allegations and has posted what she says are text messages between herself and Ellison.

“He wouldn’t lie about his own mom,” she said.

What my son said is true. Every statement he made was true.@keithellison, you know you did that to me. I have given every opportunity to get help and heal. Even now, u r willing to say my son is lying and have me continue to leak more text and info just so others will believe him

Luis Miranda, a former DNC communications director, told NPR he thought the organization “has no choice but to suspend him at a minimum until they figure out what’s going on.”

“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.”
