Impeachment proceedings began yesterday – in the House. For comment we turn to John Nichols.Next up, it’s the unhappy 100th anniversary of the Palmer Raids – we talk with Adam Hochshild about deportation – in 1919 and today.Also, we talk with Howard Rodman about his novel "The Great Eastern." Ricky Jay's review reads: "it's a book of confabulations, real and imagined. Surprises on every page. A splendid and notable achievement."
