Last week, prosecutors began arguments again Paul Manafort, the former Trump campaign chairman, in the first trial to come out of Robert Mueller's Russia investigation. Manafort has been indicted for a litany of financial crimes stemming from his work, from 2004 to 2014, as an advisor to a pro-Putin party in Ukraine. Meanwhile, President Trump continues to call the Mueller investigation a politically-motivated “witch hunt”. Susan B. Glasser joins David Rohde to discuss the courtroom spectacle of the Manafort Trial, how Mueller is building his case, and what's at stake for the President.
