(August 8, 1981 - April 6, 2000) (divorced) (2 children)
In the spring of 1980, Gingrich left his wife after beginning an affair with Marianne Ginther.
In 1981, six months after his divorce from his first wife was final, Gingrich wed Marianne Ginther. Marianne helped control their finances to get them out of debt. She was also coauthor of his 1984 book Window of Opportunity: A Blueprint for the Future. She did not, however, want to have the public life of a politician's wife. Gingrich's daughter Kathy Lubbers described the marriage as "difficult".
In 1993, while still married to Marianne, Gingrich began an affair with House of Representatives staffer Callista Bisek, more than two decades his junior. Gingrich and his second wife were divorced in 2000. The marriage produced no children. On January 19, 2012, Marianne Ginther Gingrich alleged in an interview on ABC's Nightline that she had declined to accept Gingrich's suggestion of an open marriage.
