WASHINGTON — As President Trump met with advisers in the Oval Office in May 2017 to discuss replacements for the F.B.I. director he had just fired, Attorney General Jeff Sessions slipped out of the room to take a call.
When he came back, he gave Mr. Trump bad news: Robert S. Mueller III had just been appointed as a special counsel to take over the investigation into Russia’s interference in the 2016 presidential election and any actions by the president to impede it.
Mr. Trump slumped in his chair. “Oh, my God,” he said. “This is terrible. This is the end of my presidency. I’m fucked.”
