A most unusual podcast this week! First, White House lawyer Ty Cobb, who is in charge of the Russian investigation for the presidency, gives an exclusive wide-ranging and fascinating interview about the current state of play with the special prosecutor's investigation. Moments later, news broke that he was retiring as White House lawyer and we quickly got him back on the line to explain and to outline what comes next.
