Robert S. Mueller III, the FBI director who transformed the nation’s premier law enforcement agency into a terrorism-fighting force after the Sept. 11, 2001, attacks and who later became special counsel in charge of investigating ties between Russia and Donald Trump’s presidential campaign, has died at the age of 81.

A Legacy of Public Service

Transforming the FBI After 9/11

Following the September 11th attacks, Mueller overhauled the FBI’s mission, shifting its focus from domestic crime to preventing terrorism as reported by the Associated Press. This involved a significant restructuring of the bureau to meet the evolving law enforcement needs of the 21st century.
