What is the CIA For? (Tim Wener)

The Pulitzer Prize winner discusses his new book about the role of the CIA since 9-11. What should they be doing? What are they getting wrong? It turns out that CIA is really bad at some things - torture and running prisons around the world. They are fairly good at other things - namely espionage and intelligence. And Weiner ends with a straight-up warning about the perils of making the CIA a play toy for Donald Trump.
