The first clip in Marianne Gingrich's "explosive" interview is out, and with ex-husband Newt surging two days before South Carolina's primary, she's hitting hard at his moral compass. She describes the moment he confessed his six-year affair with current wife Callista: "I said to him, 'We've been married a long time.' And he said, 'Yes, but you want me all to yourself. Callista doesn't care what I do.'" Prompted by ABC's Brian Ross to clarify, Marianne says, "He was asking to have an open marriage ... that I accept the fact that he has somebody else in his life." How did she respond? "No. No. That is not a marriage."
It gets slightly more icky from there, with Marianne Gingrich describing her "shock" upon learning he frequently brought Callista to "my bedroom in our apartment in Washington." She recalls: "He always called me at night, and always ended with 'I love you.' Well, she was listening." Newt Gingrich, meanwhile, is calling the interview "old news."
