Former Governor of New Jersey Chris Christie sat down with George Stephanopoulos on ABC News This Week to discuss his former boss’s new book, A Higher Loyalty. When Christie served as U.S. attorney for New Jersey, former FBI Director James Comey was his boss at the U.S. Department of Justice. In the past, Christie has shed positive light on Comey’s leadership style and his integrity.

According to Gov. Christie, at one point in their relationship Comey said to him, "Chris, its much harder to hate up close.” On that comment, Christie said “It's one of the smartest things anybody ever told me about leadership.”

But today, Gov. Christie admonished Comey for his newfound ego.
