FBI · Robert Mueller · Russia Investigation · Special Counsel
Robert S. Mueller III, the former FBI Director who transformed the agency into a terrorism-fighting force after the September 11, 2001 attacks and later served as Special Counsel investigating Russian interference in the 2016 election, died at 81 on March 20, 2026.
Mueller's 12-year tenure at the FBI began just one week before 9/11, prompting a significant shift in the bureau's mission from domestic crime to counter-terrorism. As Special Counsel, he led a two-year investigation into ties between Russia and Donald Trump's presidential campaign, concluding Russia interfered on Trump's behalf and the campaign welcomed the assistance.
The 448-page report, released in April 2019, found insufficient evidence of a criminal conspiracy and did not make a prosecutorial decision on obstruction of justice, citing Department of Justice policy against indicting a sitting president. Despite constant criticism from then-President Trump, Mueller maintained a silent, buttoned-down demeanor throughout the inquiry.
His distinguished career included service as a Marine in Vietnam, a federal prosecutor, and head of the Justice Department's criminal division, earning praise from Presidents George W. Bush and Barack Obama for his dedication to public service and the rule of law.
