THE WOODLANDS, TEXAS — Republican presidential contender Herman Cain on Saturday vowed to answer no more questions about decade-old sexual harassment allegations and blamed journalists for the claims that have dogged his campaign.

Growing agitated with reporters after a one-on-one debate with rival Newt Gingrich, the former business executive suggested the reporters who asked questions about the allegations were unethical.

Asked if he planned to never answer questions about the incidents, he was certain. “You got it,” he snapped, even as the allegations leave plenty of doubts about Cain’s candidacy.
