FILE - In this Feb. 9, 1995 photo, Marianne Gingrich, wife of House Speaker Newt Gingrich, is photographed in Jerusalem, Israel. Dredging up a past that Newt Gingrich has worked hard to bury, the GOP presidential candidate's ex-wife says Gingrich asked for an "open marriage" in which he could have both a wife and a mistress. In an interview with ABC News' "Nightline" scheduled to air Thursday, Jan. 19, 2012, Marianne Gingrich said she refused to go along with the proposal that she share her husband with Callista Bisek, who would later become his third wife.
