Vanity Fair contributing editor Bethany McLean joins us to discuss her recent article, “The True Story of the Comey Letter Debacle.” McLean reports on the power struggle between Attorney General Loretta Lynch and F.B.I. director James Comey. She looks at how the F.B.I. director who was once held up as a law-enforcement hero squares with the man whose infamous letter, released two days before the election, enraged both parties and led to serious questions about his motives.
