President Donald Trump’s lawyers have now concluded his impeachment defense on the floor of the Senate. A verdict—probably acquittal—is nigh. Or is it? In these final days and hours of the Trump impeachment saga, new bombshells keep exploding. A leak this week of a draft book manuscript by former National Security Adviser John Bolton's book heightened pressure on the handful of Republican senators able to green-light new evidence, or allow the trial to come to a speedy conclusion. On today’s show, you’ll hear from Mother Jones DC bureau chief David Corn who attempts to answer questions at the center of this week's drama: What does John Bolton know? Will any Republican Senators defect from the party line? What's the deal with Kenneth Starr and Alan Dershowitz? The Trump presidency has been marked by scandal, corruption, and dirty deals. These next few days will determine whether it can survive impeachment intact.
