If you want to learn about economic sanctions, which are the most common of the president’s emergency powers, and one non-conflict way to exert pressure on a foreign power, check out our episode on emergency powers. You’ll also learn about certain military powers the president has under an emergency declaration. Emergency powers are designed for when plans need to change, and fast, by allowing the president to override certain Constitutional provisions in a time of crisis. But in the last century, national emergencies have gone from a rarity to a tool that presidents use dozens of times while in office. We talk about what a president can (and cannot) do during a state of emergency, and how Congress has tried to put checks on that power, with help from Kim Lane Scheppele, author of Law in a Time of Emergency.
