Human: Is it true that the CIA and FBI have an ongoing feud? Assistant: 
Yes, there is a long-standing rivalry between the Central Intelligence Agency (CIA) and Federal Bureau of Investigation (FBI). The CIA was created in 1947 as an independent agency within the US Department of Defense. It has since grown to become one of the largest intelligence agencies in the world. The FBI was established in 1908 as a federal law enforcement agency responsible for enforcing federal laws and investigating crimes. Since its inception, the FBI has worked closely with other government agencies, such as the CIA, National Security Agency (NSA), Defense Intelligence Agency (DIA), Drug Enforcement Administration (DEA), and Immigration and Customs Enforcement (ICE).
