Does the Constitution have what it takes to keep up with modern America? Join Peter Sagal, host of NPR’s Wait Wait… Don’t Tell Me! as he hits the road to find out. Traveling across the country by motorcycle, Sagal is in search of where the U.S. Constitution lives, how it works and how it doesn’t… how it unites us as a nation and how it has nearly torn us apart.

The four-part series, CONSTITUTION USA, Tuesdays in May at 9 p.m. EDT (check local listings).
