Robert Mueller, former FBI director and special counsel, dies at 81

Robert Mueller, the former FBI director and special counsel who led the investigation into Russian interference in the 2016 presidential election, has died at 81. Mueller served as FBI director for 12 years, making him the second-longest serving director in the agency's 114-year history, and later spent nearly two years as special counsel investigating potential coordination between the Trump campaign and Russia. His tenure as special counsel produced a 448-page report that detailed extensive Russian interference efforts and multiple instances where President Trump sought to impede the investigation, though Mueller did not reach a prosecutorial conclusion on obstruction. Mueller's leadership at the FBI during the post-9/11 era also shaped the bureau's transformation into a national security-focused agency. His death removes a central figure from one of the most consequential investigations in modern American politics.
