Robert S. Mueller III, who led the FBI for 12 years and served as special counsel investigating Russian interference in the 2016 presidential election, died on Friday at the age of 81. Mueller was credited with transforming the FBI into a 21st-century intelligence service, and his investigation into the Trump campaign's ties to Russia was politically explosive, though he ultimately concluded that he could neither absolve nor accuse the president of a crime.

Why it matters

Mueller's tenure as FBI director and his high-profile role as special counsel overseeing the investigation into Russian election interference made him a central figure in some of the most significant political events of the past two decades. His death marks the passing of a towering law enforcement and legal figure who left a lasting impact on the FBI and the country.

The details

Mueller became FBI director just a week before the 9/11 attacks and went on to impose major structural and cultural changes at the bureau, seeking to transform it into a 21st-century intelligence service. As special counsel, he brought politically explosive indictments as part of his investigation into Russia's attack on the 2016 election, though he ultimately concluded that he could neither absolve nor accuse President Trump of a crime.

  • Mueller became FBI director on September 4, 2001, just a week before the 9/11 attacks.
  • Mueller was named special counsel on May 17, 2017, eight days after President Trump fired FBI Director James Comey.
