After all, the second ex-wife of GOP presidential contender Newt Gingrich gave an extensive interview in 2010 to Esquire, and the formerly married twosome haven’t been exactly close since then. 

Newt has been faithfully (he says) wed to wife number three, Callista Bistec Gingrich, since 2000.  Won’t anything Marianne has to say to investigative correspondent Brian Ross about her rancorous divorce from the caddish conservative be a stale retelling of  her ex’s flagrant cheating? Personally, I’ve always been curious about that sworn interview (sealed by the Georgia court) that Callista gave to lawyers about her affair with the former speaker.  As the respondent, Marianne read the details and no doubt knows every answer by heart.  

What is sure to be new from Marianne is the format; she has spilled a lot of beans in the past but never while facing a key light and wearing a microphone.

As a former TV news producer, I remember the first law of television: If news doesn’t happen in front of a camera, it doesn’t count.
