Best-selling author Michael Wolff has spent months inside President Trump's West Wing (often unsupervised!), listening to senior officials pour out real-time accounts of their internal battles, maneuvering and frustrations. The result is a juicy, explosive book, "Fire and Fury: Inside the Trump White House," to be published Jan. 9 by Henry Holt.
What we're hearing: My conversations with the West Wing show there's already a frenzy inside to figure out who told Wolff what. Wolff tells me key players have been barraging him with calls, trying to figure out what his sources said about them: "It's the fundamental dynamic of this White House — people divided against each other."
