Robert Mueller, former special counsel who investigated Russian interference in the 2016 presidential election, died Friday.
Mueller, also former director of the Federal Bureau of Investigation, was 81.
“With deep sadness, we are sharing the news that Bob passed away” on Friday night, his family said in a statement Saturday. “His family asks that their privacy be respected.”
MS Now first reported the news on Saturday.
Mueller concluded in 2019 that Russia interfered in the election in an effort to influence voters towards President Donald Trump’s 2016 campaign.
The Russia investigation and Mueller himself swiftly became lightning rods for Trump, who over the years has repeatedly called the probe a “witch hunt” and a “hoax.”
Shortly after Mueller’s death was reported, Trump said in a Truth Social post, “Good, I’m glad he’s dead.”
He added, “He can no longer hurt innocent people!”
From FBI director to special counsel
Mueller was the second-longest-serving director in FBI history, behind only J. Edgar Hoover. He began his tenure just one week before the Sept. 11 attacks in 2001, which became the catalyst for turning the agency’s priority from solving domestic crimes to fighting terrorism.
Mueller stayed in the post for 12 years after then-President Barack Obama asked him to remain on following his 10-year term. He entered private practice after leaving in 2013.
In 2017, he returned to public service after being appointed by Deputy Attorney General Rod Rosenstein to serve as special counsel in the Trump-Russia inquiry.
Mueller’s stern visage and taciturn demeanor matched the seriousness of the mission as his team spent nearly two years quietly conducting one of the most consequential yet divisive investigations in Justice Department history. He held no news conferences and made no public appearances during the investigation, remaining quiet despite attacks from Trump and his supporters and creating an aura of mystery around his work.
All told, Mueller brought criminal charges against six of the president’s associates, including his campaign chairman and first national security adviser.

His 448-page report, released in April 2019, identified substantial contacts between the Trump campaign and Russia but did not allege a criminal conspiracy. He laid out damaging details about Trump’s efforts to seize control of the investigation, and even shut it down, though Mueller declined to decide whether Trump had broken the law, in part because of department policy barring the indictment of a sitting president.
But, in perhaps the most memorable language of the report, Mueller pointedly noted: “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 nebulous conclusion did not deliver the knockout punch to the administration that some Trump opponents had hoped for, nor did it trigger a sustained push by House Democrats to impeach the president — though he was later tried and acquitted on separate allegations related to Ukraine.
The outcome also left room for Attorney General William Barr to insert his own views. He and his team made their own determination that Trump did not obstruct justice, and he and Mueller privately tangled over a four-page summary letter from Barr that Mueller felt did not adequately capture his report’s damaging conclusion.
Mueller deflated Democrats during a highly anticipated congressional hearing on his report when he offered terse, one-word answers and appeared uncertain in his testimony. Frequently, he seemed to waver on details of his investigation. It was hardly the commanding performance many had expected from Mueller, who had a towering reputation in Washington.
Over the next months, Barr made clear his own disagreements with the foundations of the Russia investigation, moving to dismiss a false-statements prosecution that Mueller had brought against former national security adviser Michael Flynn, even though that investigation ended in a guilty plea.
Mueller’s tenure as special counsel was the capstone of a career spent in government.
Vietnam veteran and career criminal prosecutor
Mueller was born in New York City and grew up in a well-to-do suburb of Philadelphia.
He received a bachelor’s degree from Princeton and a master’s degree in international relations from New York University. He then joined the Marines, serving for three years as an officer during the Vietnam War. He led a rifle platoon and was awarded a Bronze Star, Purple Heart and two Navy Commendation Medals. Following his military service, Mueller earned a law degree from the University of Virginia.
Mueller became a federal prosecutor and relished handling criminal cases. He rose quickly through the ranks in U.S. attorneys’ offices in San Francisco and Boston from 1976 to 1988. Later, as head of the Justice Department’s criminal division in Washington, he oversaw a range of high-profile prosecutions that chalked up victories against targets as varied as Panamanian dictator Manuel Noriega and New York crime boss John Gotti.
In a mid-career switch that shocked colleagues, Mueller threw over a job at a prestigious Boston law firm to join the homicide division of the U.S. attorney’s office in the nation’s capital. There, he immersed himself as a senior litigator in a bulging caseload of unsolved drug-related murders in a city rife with violence.
Mueller was driven by a career-long passion for the painstaking work of building successful criminal cases. Even as head of the FBI, he would dig into the details of investigations, some of them major cases but others less so, sometimes surprising agents who suddenly found themselves on the phone with the director.
“The management books will tell you that as the head of an organization, you should focus on the vision,” Mueller once said. But “for me there were and are today those areas where one needs to be substantially personally involved,” especially in regard to “the terrorist threat and the need to know and understand that threat to its roots.”
Two terrorist attacks occurred toward the end of Mueller’s watch: the Boston Marathon bombing and the Fort Hood shootings in Texas. Both weighed heavily on him, he acknowledged in an interview two weeks before his departure.
“You sit down with victims’ families, you see the pain they go through and you always wonder whether there isn’t something more” that could have been done, he said.
