Which agency serves as both an investigative body and a domestic intelligence agency in the U.S.?

The Federal Bureau of Investigation (FBI) serves as both an investigative body and a domestic intelligence agency in the United States. The FBI's primary mission encompasses several critical areas, including investigating federal crimes, enforcing laws, and protecting the nation from threats such as terrorism, cybercrime, and organized crime. As a part of its intelligence function, the FBI gathers and analyzes information to prevent potential threats to national security, making it an essential component of the U.S. intelligence community.

The agency operates under a unique dual responsibility, allowing it to conduct criminal investigations and national security operations simultaneously. This capacity distinguishes the FBI from other agencies, which may focus on specific areas such as drug enforcement, public health, or military operations. In contexts where both crime prevention and intelligence gathering are paramount, the FBI effectively bridges these critical functions, reinforcing its status as a vital law enforcement and intelligence entity within the U.S. government.
