WAMC's Dr. Alan Chartock discusses how a draft of a new memoir by former national security adviser John Bolton is renewing calls for witness testimony at President Trump's impeachment trial.
Dr. Chartock also comments on a contentious interview between NPR's Mary Louise Kelly and Secretary of State Mike Pompeo, and a newly-surfaced video showing President Trump with Lev Parnas and Igor Fruman, the indicted associates of Rudy Giuliani.
