I admit to the guilty pleasure of finishing Michael Wolff’s Fire and Fury this weekend. Given that the release of this book finished off Steve Bannon at Breitbart because of an angry Donald Trump, it might well have been titled, Fired by the Furious. But the saga that Wolff sets out, based on extraordinary White House access, should be most alarming because the proof that Trump’s not fit for duty is pouring out from his own inner circle.
