NEW YORK — An ABC News executive tells The Associated Press that the network has interviewed Newt Gingrich's second wife and is likely to air the segment Thursday on "Nightline."
The interview looms before the South Carolina primary Saturday, when the former House speaker is trying to topple front-runner Mitt Romney in the Republican presidential race.
The ABC News executive did not indicate what the ex-wife, Marianne, said in the interview and spoke on the condition of anonymity because the plans for airing the interview were tentative.
Marrianne has said Gingrich proposed to her before the divorce from his first wife was final in 1981. Her marriage to Gingrich ended in divorce in 2000. Gingrich admitted he'd already taken up with Callista Bisek, his third wife.
Gingrich has said he has no relationship with his second wife.
