The reporter who conducted that interview, ABC Chief Investigative Correspondent Brian Ross, told WMAL's Morning Majority program that Marianne Gingrich claims her ex-husband wanted an 'open marriage.' "He came to her and said, 'I want to stay married to you and still have an affair with Calista, his current wife," said Ross. "According to Marianne, he said 'You need to share me,' and she said 'I don't want to share,' and the marriage ended," he added.
