The attorney for Karen Monahan claimed there’s “substantial corroborative evidence” to prove his client was mentally and physically abused by Democratic Rep. Keith Ellison of Minnesota, on “Fox & Friends” Thursday.

Monahan, who is Ellison’s ex-girlfriend, accused him of often shouting obscenities at her and claimed he has a penchant for domestic violence. (RELATED: Daily Caller’s Stephanie Hamill Accuses Democrats Of Ignoring Allegations Against Keith Ellison)

Ellison is running for Minnesota attorney general in November and is now considering stepping down from his post as deputy chair of the Democratic National Committee.

“The DNC kicked this matter, even though Mr. Ellison is the deputy chair of the national Democratic committee, they kicked the matter to the state Democratic Party,” attorney Andrew Parker said. “The state Democratic Party decided to hire their own lawyer to investigate their nominee for attorney general in the state of Minnesota.”

Parker claimed the investigators were biased and wanted a positive result for Ellison, so he could continue his campaign for attorney general.

“After going through an investigation the investigator did find that it was unsubstantiated, but if you read the investigative report, there is substantial corroborative evidence,” he continued. “Even the investigator stated that Ms. Monahan not only testified credibly but the witnesses that she identified corroborated her story and they testified credibly.”

Co-host Ainsley Earhardt pushed Parker to be specific with his evidence and he said in addition to credible testimony from four witnesses, Monahan has text messages referencing an attack.

“As it relates to the evidence, she identified four witnesses, all of whom were interviewed, all of whom were very credible according to the investigator,” he said Thursday. “In addition, text messages regarding the attack were sent from Ms. Monahan a year and a half before this ever became public — were sent by Ms. Monahan to Mr. Ellison.”
