Robert S. Mueller III, the FBI director who remade the bureau into a terrorism-focused agency after the Sept. 11, 2001, attacks and later served as special counsel investigating ties between Russia and Donald Trump’s 2016 campaign, has died. He was 81.
“With deep sadness, we are sharing the news that Bob passed away on Friday night,” his family said in a statement Saturday, asking that their privacy be respected. The FBI did not immediately respond to a request for comment.
Mueller began a 12-year tenure at the FBI just one week before the Sept. 11 attacks, having been nominated by Republican President George W. Bush. The attacks abruptly shifted the bureau’s priority from solving past crimes to preventing terrorism, a transformational change that required revamping intelligence capabilities, technology and partnerships at home and abroad. Under Mueller, some 2,000 of the bureau’s roughly 5,000 criminal agents were moved into national security work.
The shift produced both successes and controversies. The FBI disrupted plots and pursued high-profile criminal cases such as the fraud prosecution of Bernie Madoff, but inspector general reviews later found problems, including instances where the bureau bypassed legal safeguards to obtain phone records. Mueller also decided the FBI would not take part in abusive interrogation techniques, though communicating that policy to the rank and file faltered. Efforts to modernize the bureau’s IT systems ran over budget and behind schedule.
A former Marine who served in Vietnam and was awarded a Bronze Star, Purple Heart and two Navy Commendation Medals, Mueller was a Princeton graduate with a master’s in international relations from NYU and a law degree from the University of Virginia. He rose through U.S. attorney’s offices in San Francisco and Boston and later led the Justice Department’s criminal division, overseeing prosecutions ranging from Manuel Noriega to John Gotti. Known for a meticulous, old-school work ethic, Mueller often dug into case details and was regarded as apolitical in his role, at times clashing with the Bush administration over surveillance practices. In a notable 2004 episode, he and then-Deputy Attorney General James Comey blocked efforts to reauthorize a secret wiretapping program at the bedside of a hospitalized attorney general.
After leaving the FBI in 2013 — the second-longest-serving director after J. Edgar Hoover, having stayed on at the request of President Barack Obama — Mueller returned to private practice until Deputy Attorney General Rod Rosenstein appointed him special counsel to investigate possible coordination between the Trump campaign and Russia.
Mueller’s special counsel team spent nearly two years investigating. In April 2019 he submitted a 448-page report that documented numerous contacts between Trump associates and Russians but did not allege a criminal conspiracy. The report detailed efforts by President Trump to influence and impede the investigation and concluded it could not exonerate him on obstruction-of-justice questions: “If we had confidence after a thorough investigation of the facts that the president clearly did not commit obstruction of justice, we would so state. Based on the facts and the applicable legal standards, we are unable to reach that judgment.”
The report led to criminal charges against six of Trump’s associates, including his campaign chairman and first national security adviser. Its ambiguous conclusion disappointed some who sought a definitive legal judgment. Attorney General William Barr later wrote a four-page summary of the report that Mueller privately criticized as failing to capture the report’s findings; Barr and his team ultimately concluded Trump did not obstruct justice. Barr also moved to dismiss a false-statements prosecution of former national security adviser Michael Flynn, despite Flynn’s initial guilty plea.
Mueller’s congressional testimony after the report was terse and often consisted of single-word answers, a performance that undercut expectations for a forceful public accounting. The special counsel period nonetheless marked a capstone to a long government career.
Toward the end of his FBI tenure, Mueller confronted other major domestic attacks, including the Boston Marathon bombing and the Fort Hood shootings, events he later said weighed heavily on him when meeting victims’ families. He left a legacy of transforming the bureau into a national security agency while maintaining a reputation for steady professionalism.
Following the announcement of his death, former President Trump posted on social media: “Robert Mueller just died. Good, I’m glad he’s dead. He can no longer hurt innocent people!”
Mueller’s life combined military service, prosecutorial rigor and long stewardship of the nation’s top law enforcement agency. His family’s request for privacy will be honored as details about his death and plans are expected to be released in due course.
