In May 2017, Robert Mueller was tapped to lead an inquiry into Russian interference in the 2016 presidential election, coordination by foreign agents with the President of the United States and his campaign, and obstruction of justice by President Donald J. Trump. Mueller assembled the nation's top prosecutors, and for the next twenty-two months the investigation was the subject of endless anticipation and speculation. In Where Law Ends, Andrew Weissmann—a key player in the Special Counsel's office and head of the Manafort investigation—finally pulls back the curtain to reveal exactly what went on inside the investigation, including the debates, deliberations, and mistakes of the team, as well as the external efforts by the President and Attorney General Barr to manipulate the investigation to their political ends.
