Joint Terrorism Task Force

A Joint Terrorism Task Force (JTTF) is an American locally-based multi-agency partnership between various federal, state, and local law enforcement agencies tasked with investigating terrorism and terrorism-related crimes, led by the Federal Bureau of Investigation and U.S. Department of Justice. The first JTTFs were established in the 1980s and 1990s, with their numbers increasing dramatically after the September 11 attacks.
