Robert S. Mueller III, the FBI director who transformed the nation’s premier law enforcement agency into a terrorism-fighting force after the Sept. 11, 2001, attacks and who later became special counsel in charge of investigating ties between Russia and Donald Trump’s presidential campaign, has died

Trump posted on social media after the announcement of Mueller’s death: “Robert Mueller just died. Good, I’m glad he’s dead.” The Republican president added, “He can no longer hurt innocent people!”
