WASHINGTON, March 30 (UPI) -- FBI Director Robert Mueller, the longest serving FBI head since J. Edgar Hoover, says the agency's job is more complicated than ever before.
Mueller said since the Sept. 11, 2001, terror attacks, the FBI "has transformed itself into a threat-driven, intelligence-led national security agency" with a mission of protecting the nation from terrorism, fraud, public corruption, and international and violent organized crime.
