Newt HAD to know that this would come up...He has to have something prepared to deal with this. No Romney! Ever!
I’m sure he knew it was just a matter of time. Especially after her quote in 1995.
I believe that Newt was prepared for this and this will be the time that Callista rises to take on the story.
Newt won’t have to say much with Callista being the point person.
