Who? What? Are we talking about Thomas Jefferson? You bet.

There is an ongoing debate among historians (and other people, lots of other people) about old Tom's place in American history. Everyone admires the Declaration of Independence and "all men are created equal." But then there's that slavery thing. Ouch.

We'll talk with Paul Finkelman, author of "Slavery and the Founders," who is among Jefferson's harsher critics. Paul doesn't pull any punches. But don't worry, this is just one conversation among many that we've had, and will have again, about a remarkable, contradictory man who is arguably our most troubling Founder.
