While Newt Gingrich’s daughters denied their father ever asked for an “open marriage,” his ex-wife Marianne (who is not their mother) claimed in a Nightline interview that Newt once asked if she would share him with his then-mistress, Callista, when Marianne discovered their six-year affair. “I said to him, ‘we’ve been married a long time,’ and he said to me ‘you want me all to yourself, Callista doesn’t care what I do,’” Marianne Gingrich said. “He was asking me for an open marriage, and I refused.” Marianne and Newt divorced following the revelation, and Newt went on to marry Callista—and he converted to Catholicism as well. At a debate in Iowa, Newt acknowledged his past affair, saying “I’ve said upfront that I’ve made mistakes at times. I’ve had to go to God for forgiveness.”
