The feud between former President Trump and the nation’s highest-ranking military officer, Gen. Mark Milley, played a key role in the historic indictment handed down last week over Trump’s alleged criminal mishandling of classified documents. “Trump and Milley had a particularly fractious relationship, as stormy as any in modern times,” said Feaver, who is close to Milley. The excerpt also detailed how Milley worked aggressively to dissuade Trump from attacking Iran — a characterization Trump sought to dispel in a conversation that is now at the center of the federal case against the former president.
