It was March of 2017 and cold and bleary in Washington when Trump shouted to his advisers, “Where’s my Roy Cohn?” His anger was fueled by a common catalyst—the president believed one of his underlings to be less than absolutely loyal. Even worse, it was his lawyer.

Or, rather, it wasn’t. The president was bellowing at his aides because Attorney General Jeff Sessions had just announced his recusal from the investigation into Russian interference in the 2016 election. The attorney general is not the president’s lawyer. The attorney general is not supposed to be loyal to the president.
