Monday, January 20, 2020: The White House releases their defense brief

The Trump legal team files its defense brief with the senate, arguing the president did nothing wrong - and that the Democrats' case does not meet the constitutional test for impeachment and removal. Plus, testing time for Mitch McConnell. The Senate Majority Leader wants a quick trial, with no new witnesses or evidence. Democrats vow to fight that plan, but need a handful of Republicans to break with their president and party to succeed. And the 2020 democrats are courting black voters on this Martin Luther King Jr holiday, with the first votes two weeks from today. Today's panel: Julie Pace with the Associated Press, Dan Balz with the Washington Post, Francesca Chambers with McClatchy, and Politico's Heather Caygle. Also on the show: CNN's Carrie Cordero, Phil Mattingly, and Jessica Dean.
