Monday, December 23, 2019: An impeachment stalemate

The holiday week begins with a major stalemate over impeachment. And a new challenge is thrown at House Democrats today as they pursue the testimony of former White House Counsel Don McGann. It's another result of their impeachment of the president. Plus on the campaign trail, Senator Elizabeth Warren seems to have her own ghosts in the wine cave. A look at her past fundraising contradicts her attack on Pete Buttigieg. Who will come out the winner in this war of words? John King is out today, Manu Raju guest hosts. Today's panel: CNN's Sara Murray, Rachael Bade with The Washington Post, Olivier Knox with Sirius XM, and Josh Dawsey with The Washington Post. Also on the program: CNN's Kyung Lah.
