Russiagate in Review; plus Jane Mayer: Would Pence Be Worse?

Russiagate is basically a political corruption scandal, says David Klion. The basic facts have been obvious for a long time—and they should bring down Trump’s presidency. Also: we ask Jane Mayer of the New Yorker what may be the most important question of the year: Would Pence be worse? Plus: Why are Danes so much happier than Americans? Is it just because Donald Trump is NOT their president? Joshua Holland says there’s more to it than that. And we also have a history segment today: Sean Wilentz talks about the place of slavery in the origins of the United States--his new book is "No Property in Man."
