Brian Kalt is a professor of law at Michigan State University. In 2012, he wrote "Constitutional Cliffhangers, " a book about all of the gaps in and the potentially disruptive interpretations of the text of the U.S. Constitution. His new book, "Unable: The Law, Politics, and Limits of Section 4 of the Twenty-Fifth Amendment," is about the mere 270 words that comprise that section. David Priess spoke with Brian about the need for something better than what the original Constitution said about presidential incapacity; the drafting of the 25th Amendment and the discussions around its various provisions; how the media, TV shows, movies, and books often get important parts of the 25th Amendment wrong; and how an invocation of the 25th Amendment's 4th section would actually work.
