Clay Jenkinson, American humanities scholar, author and educator (and familiar to WGN Radio listeners as Thomas Jefferson and Teddy Roosevelt), joins John Williams to discuss the new Ken Burns documentary, “Ben Franklin.” Clay talks about his work on the documentary, what we should know about Ben Franklin, why he was regarded as a second Newton, how the Founding Fathers differed from our current politicians, and if there is anyone in public life now who would be similar to Ben Franklin.
