The South Carolina feud between Barack Obama and Hillary Clinton is not letting up ahead of this Saturday's critical primary.
Some are saying former President Bill Clinton has become the Clinton campaign's attack dog there, taking aim at Barack Obama and the media.
Bill Clinton says Obama has put out a "hit job" on him.
He also lashed out, telling one reporter "shame on you!" after the journalist asked about the role race is playing in the South Carolina campaign.
Meanwhile, Obama is not backing down from a radio ad that says quote, "Hillary Clinton will say anything to get elected."
