Inauguration Day means it's almost time for the nuclear football to shift from one president to another. But how does that work, exactly?

Host Geoff Wilson sits down with Stephen Schwartz, nonresident Senior Fellow at the Bulletin of the Atomic Scientists and author of Atomic Audit, to get some answers.
