Aside from busting out in an impromptu song on the campaign trail, Republican frontrunner Herman Cain instead spent the day trying to explain away past allegations. In full-on damage control mode, the former Godfather's Pizza CEO said he's the victim of a "witch hunt" after Politico first broke the story of sexual harassment accusations. NBC News confirmed two women accused Herman Cain of inappropriate sexual conduct while he was CEO of the National Restaurant Association in the 1990s and at least one of them received a financial settlement.Throughout the day, Cain offered conflicting answers on whether he knew about any agreements with these women who still remain anonymous and the alleged behavior in question.At the National Press Club today, Cain found himself adamantly declaring that he "never sexually harassed anyone." He told FOX News, "I was falsely accused while I was at the National Restaurant Association."But in a new interview with PBS' Judy Woodruff, Cain was more ambiguous when asked about any incidents of inappropriate behavior saying that he believes there was no inappropriate behavior on his part. Cain then added, "as you would've imagined, it's in the eye of the person who thinks maybe I crossed the line." The debacle all started when Politico reported that in the past two women complained of sexually suggestive behavior by Cain which made them angry and uncomfortable.Cain has been married to his wife Gloria for 43 years.
