Robert Mueller, the longtime law enforcement official who led the investigation into Russian interference in the 2016 U.S. presidential election, has died at the age of 81.
Mueller’s family confirmed his death Friday night, asking for privacy as they mourn. The cause of death was not immediately disclosed.
Mueller served as director of the Federal Bureau of Investigation from 2001 to 2013, taking the role just days before the September 11 terrorist attacks. During his tenure, he played a key role in transforming the FBI into a modern counterterrorism agency focused on preventing future attacks.
He later returned to the national spotlight in 2017 when he was appointed special counsel to investigate Russian interference in the 2016 election and potential ties between Moscow and the campaign of Donald Trump.
The investigation dominated much of Trump’s first presidential term and drew fierce criticism from the president and his allies. After news of Mueller’s death, Trump posted on Truth Social: “I’m glad he’s dead. He can no longer hurt innocent people!”
Despite political controversy surrounding the probe, Mueller was widely praised by former colleagues and political leaders for his decades of public service.
George W. Bush, who appointed Mueller as FBI director in 2001, said he was “deeply saddened” by the news and credited him with helping guide the agency through one of the most challenging periods in American history following the 9/11 attacks.
Barack Obama also paid tribute, calling Mueller “one of the finest directors in the history of the FBI” and praising his commitment to the rule of law.
Former FBI director James Comey, who succeeded Mueller and whose dismissal by Trump helped trigger the special counsel investigation, described him as “a great American” and a mentor.
Born in 1944, Mueller studied politics at Princeton University before serving in the U.S. Marines during the Vietnam War. As a platoon leader, he was wounded in combat and received several decorations, including a Bronze Star for valor and a Purple Heart.
After the war, he earned a law degree from the University of Virginia and began a long career in public service and federal law enforcement.
Mueller retired from the FBI in 2013 after more than a decade leading the agency. He is survived by his wife of nearly 60 years, Ann Cabell Standish, their two daughters, and three grandchildren.
