Paul Farhi [@farhip], Washington Post media reporter, and Mike Spies [@mikespiesnyc], ProPublica reporter, on John Solomon's role in the impeachment saga. Listen.  2. Corey Robin [@CoreyRobin], writer and political scientist at Brooklyn College and the CUNY Graduate Center, on all that we've missed (or ignored) about Justice Clarence Thomas.
