William Henry Harrison with Sharon McMahon

What happens when a sitting United States president dies in office for the very first time, and the Constitution doesn't explicitly state if the Vice President actually becomes the President?

Colleen welcomes internet superstar, podcaster, and "America’s Government Teacher" Sharon McMahon. Together, they dive into the brief, tragic presidency of William Henry Harrison—who caught a fatal illness just weeks after giving the longest inaugural address in history—and the constitutional crisis that immediately followed.

Sharon and Colleen break down how John Tyler boldly seized the full powers of the executive branch, establishing the "Tyler Precedent" that stabilized a panicking nation and fundamentally defined the line of presidential succession for centuries to come.
