News broke today that President Trump’s former "fixer" and lawyer, Michael Cohen, will betestifying in front of Congress — following his guilty plea and December sentencing to three years in prison for a range of crimes committed while working for Trump.

Earlier this week, it was reported that former Trump presidential campaign manager Paul Manafort has been accused by prosecutors of passing polling data to someone who works for Russian intelligence. That revelation provided more potential evidence of direct cooperation between the Trump 2016 campaign and the Russian government.

To discuss the latest on the Mueller investigation and what it all means, Jim Braude was joined by retired federal judge Nancy Gertner, who is now a senior lecturer at Harvard Law; and former U.S. attorney Don Stern, who worked alongside Robert Mueller both during his stint with the Department of Justice and in private practice at Hale and Dorr.
