CNN's Joan Biskupic on Nine Black Robes: Inside the Supreme Court's Drive to the Right and Its Historic Consequences.

Donald Trump fulfilled one of the decades-long goals of the American far right when he transformed the Supreme Court into a far-right majority body that will have huge impacts long after he is gone. To look at that shift, what it means for the court, and what it means for the country, we've invited Joan Biskupic into the show.  Joan is CNN's Senior Supreme Court Analyst and author of the new book Nine Black Robes: Inside the Supreme Court's Drive to the Right and Its Historic Consequences.
