WASHINGTON (AP) — An adviser to Rick Perry's presidential campaign says he never had a conversation with Herman Cain about sexual harassment, contrary to Cain's assertion.Curt Anderson tells CNN "it's just not true." Asked in an interview whether he believed Cain was lying in his statement to Forbes magazine, Anderson said, "I'm not here to add any more name-calling" in the controversy over sexual harassment allegations currently clouding the Cain campaign.Anderson, who advised Cain in a Senate campaign earlier, said: "I didn't know anything about this so it's hard to leak something you don't know anything about."Anderson adds in the interview that if one "blabs" to other people about something said in confidence, "that's unethical. And that's not the way I live my life." He repeated that he admires Cain.
