For a half century, U.S. Presidents have received daily briefings on national security threats and opportunities.
The daily book has shifted in content and emphasis with each Chief Executive. Now, there is a history of this document, a new book titled "The President’s Book of Secrets." Author David Priess served during the Bill Clinton and George W. Bush administrations as a briefer at the CIA and Desk Officer at the State Department. He’s also an Illinois Wesleyan University graduate. In this chat with Charlie Schlenker Priess talks about the evolution of the document.
