Federal Bureau of Investigation
General Information
Affiliation US Government

The Federal Bureau of Investigation (FBI), or Bureau, is the domestic intelligence and security service of the United States and a spiritual opposite to The Agency.

The Bureau is never mentioned in the Post-Credit Scenes, but Itten was likely in contact with them.

One overlooked document that was supposedly "leaked" contains reference to the FBI, as well as CIA. The question of whether or not this document is confirmed as genuine can only be answered with time.
