Canadian Intelligence Eh! Episode 326 - What was it like to brief the POTUS on intelligence?

Imagine you are the one on the hotseat who has to tell the President of the US what is happening in the world - on a daily basis. What do you tell him? Where do you get the information from? How does personality enter into the equation? How did different presidents take these briefings? All very good questions and I have just the guy to answer them, an old CIA friend who has written a very interesting book on the topic.
