Former House Speaker Newt Gingrich has filed for divorce from his wife, Marianne, after 18 years of marriage.
Papers filed Thursday in the Superior Court of Cobb County, Ga., said the couple, who were married Aug. 8, 1981, have been separated since May 10.
"The cause of the . . . separation was the fact that the marriage is irretrievably broken," the papers said. They added that Gingrich and his wife were attempting to reach a settlement "resolving all matters and controversies between them."
Marianne Gingrich's attorney, Victoria Toensing of Washington, said, "Marianne is saddened and disappointed at Newt's decision."
Gingrich reserved the right to "set forth additional grounds for divorce" if the parties could not reach an agreement.
