I'm a fan of the Daily Beast podcasts, and never miss 'Inside Trump's Brain' with Joanna and Michael Wolff.
I finally looked her up on Wiki, and turns out she's very well connected, has had prestigious jobs in many, many publications. She sounds like a cross between Tina Brown and Ghislaine Maxwell, in that she probably knows everyone there is to know (though not as much as the Zelig-like Wolff, who knows EVERYONE).
Seems like there's often tension between her and Wolff, he appears to sneer at everything and everyone, but that didn't stop people from wanting to hang out with him.
Her ex-husband sounds fascinating, and I'm going to buy one of his books.
