Kai Bird won a Pulitzer Prize for his biography of Robert Oppenheimer. The book, was the inspiration for the 2024 Academy Award winning movie. Sticking with biography as his muse, Kai has written a new book filled with spicy anecdotes entitled "American Scoundrel: Roy Cohn's Dark Journey from Joe McCarthy to Donald Trump." Roy Cohn was a disgraced lawyer who lit up the town. Among his clients, who included almost every Mafia Don you can think of, political figures and celebrities, was Donald Trump whom he served for 13 years as political strategist and guiding spirit. Trump became Cohn's apprentice in waging lawfare, the dark art of using the law to cheat or destroy other people. Journalist Ken Auletta said of Cohn, "I have never interviewed a more revolting character than Roy Cohn. He had no regard for the truth." Kai Bird tells the story.
