SPY Historian Vince Houghton sat down with Dr. Gen Lester to discuss her new book, When Should State Secrets Stay Secret. Lester’s book examines the oversight mechanisms that have developed within all three branches of government, how they interact, and what types of historical pivot points have driven change among them. She suggests ways to improve oversight mechanisms based on her expert analysis. The book also includes a fascinating chapter on the inner workings of the CIA to which a number of CIA officers contributed.
