Today, we're joined by author Derek Leebaert to discuss "UNLIKELY HEROES: Franklin Roosevelt, His Four Lieutenants, and the World They Made". The book discuss Roosevelt's only four lieutenants, Harry Hopkins, Harold Ickes, Frances Perkins, and Henry Wallace, each with their own struggles and also considered "outsiders" for reason or another. We discuss their lives and roles as Roosevelt's lieutenants and the impact each left on the presidency.
