WASHINGTON (Diya TV) — Robert S. Mueller III, the former FBI director and special counsel who led the federal investigation into Russian interference in the 2016 U.S. election, has died at the age of 81, according to statements released by officials and his family.

Mueller served as director of the Federal Bureau of Investigation from 2001 to 2013, one of the longest tenures in the agency’s history. He was appointed just days before the September 11 attacks and went on to oversee the FBI’s transformation into a counterterrorism-focused agency in the years that followed.

Before leading the FBI, Mueller held several senior roles at the U.S. Department of Justice, including serving as U.S. Attorney in San Francisco and leading the Justice Department’s criminal division. He also had a distinguished military background, serving as a Marine Corps officer during the Vietnam War, where he was awarded the Bronze Star, Purple Heart, and other honors.

Mueller returned to public service in 2017 when he was appointed special counsel to investigate Russian interference in the 2016 election and potential links between the Trump campaign and Moscow. His investigation, which lasted nearly two years, resulted in multiple indictments and convictions related to financial crimes, obstruction, and false statements.

The final report, released in 2019, concluded that Russia had interfered in the election through social media operations and hacking efforts. It did not establish a criminal conspiracy between the Trump campaign and Russia but documented numerous contacts between campaign officials and Russian individuals. The report also outlined several instances of potential obstruction of justice, leaving decisions about prosecution to Congress and the Justice Department.

Mueller’s work as special counsel placed him at the center of one of the most politically charged investigations in modern U.S. history. His testimony before Congress in 2019 drew national attention, as lawmakers debated the findings and their implications.

Throughout his career, Mueller was widely regarded as a nonpartisan law enforcement figure. He was appointed FBI director by President George W. Bush and later asked to remain in the role by President Barack Obama beyond the standard 10-year term, reflecting bipartisan confidence in his leadership.

Public officials across the political spectrum issued statements following news of his death, recognizing his decades of service in law enforcement and national security. Colleagues and former officials described him as disciplined, reserved, and committed to institutional integrity.

Mueller’s legacy includes overseeing the FBI during a critical period after 9/11 and leading a high-profile investigation that shaped national political discourse. He is survived by his wife, Ann Mueller, and their children.

Funeral arrangements have not yet been publicly announced.
