Returning to Normal: Harold Meyerson; Progressives and Biden: Alan Minsky; 'Assassins': Ella Taylor

The inauguration of Joe Biden was delightfully normal--Harold Meyerson comments on what happened -- and what didn't. Plus: Alan Minsky, Executive Director of Progressive Democrats of America, discusses the challenges facing the Congressional Progressive Caucus--and the opportunities. And our film and TV critic Ella Taylor reviews "Assassins," an amazing documentary about the assassination of the brother of Korean dictator Kim Jong Un, in Kuala Lampur airport, by two teenage girls.
