We speak once again to David Priess, former CIA Briefer and the author of The President's Book of Secrets.  While last time we spoke mostly about Presidents and intelligence, this time we get into the other people who use intelligence and how they support the President.  Priess talks about Dan Quayle, Al Gore, Dick Cheney, and other VPs as well as other officials.  In the course of the discussion, we talk about what we can know about Trump's briefings, what it's like to be a briefer, and what it's like to work with Robert Mueller.
