I have to admit this didn't make any sense to me at all. Was he claiming that he had a bunch of personal friends in attendance at all times? Did he and his wife have no privacy? In which case, they were already having something of an open marriage to begin with? It's kinda like if he claimed he was all alone in the tundra and he killed a bear with his bare hands and ate it raw to survive and then he scaled a glacier and walked 800 miles all alone back to civilization "and I have the video footage and interviews with my three cameramen and my bear wrangler to prove it!"
"Let me be quite clear. Let me be quite clear. The story is false. Every personal friend I have who knew us in that period said the story was false. We offered several of them to ABC to prove it was false. They weren't interested because they would like to attack any Republican."
Well it turns out I can stop trying to wrap my mind around how Newt had a completely traditional marriage where the couple has moments to themselves and conversations that aren't meant for anyone else, and a bunch of personal friends who could attest that no such conversation ever took place -- because they were there at all times when Newt was reassuring his wife that...oh, never mind. I can stop wondering because apparently, Newt's personal friends were actually his daughters from his first marriage.
So, Newt's daughters from his first marriage were an audience to every private moment Newt had with his wife in his second marriage? Yeah. That's better
