“Mark Block doesn’t have his facts straight,” Josh Kraushaar said in a statement obtained by CNN. “I am not related in any way to Karen Kraushaar, and I haven’t worked at Politico since June 2010.”

Cain spokesman J.D. Gordon acknowledged Block’s mistake in an email to CNN.

“Based upon information available at the time of Mr. Block’s Tuesday night interview on Fox News, the campaign was led to believe that Mr. Josh Kraushaar, currently with the National Journal and a former employee of Politico, was the son of Karen Kraushaar,” Gordon said. “Mr. Josh Kraushaar is in fact, not related to Ms. Karen Kraushaar.”
