Robert Mueller, the former FBI director known for leading the investigation into Russian interference in the 2016 U.S. presidential election, has died at age 81. He served as FBI director from 2001 to 2013, transforming the bureau’s focus toward counterterrorism after 9/11, and later led a nearly two-year special counsel investigation that charged 34 individuals but did not establish conspiracy between the Trump campaign and Russia. Mueller was widely respected for his integrity, served as a Marine in Vietnam, and had been diagnosed with Parkinson’s disease before his death.
