The handbook, rewritten in 2021, confirms a decade-old leak showcasing the bureau's collaboration with the CIA and NSA for FBI probes that may involve surveillance without court orders against people not accused of any crimes. Such probes are known as "assessments" at the FBI.

The revelations will fuel critics who have long accused the FBI of abusing its national security surveillance powers.

The FBI's partnership with U.S. intelligence agencies that are focused on foreign threats is expected to get intense scrutiny from the new Republican-run Congress. The House Permanent Select Committee on Intelligence and House Judiciary Committee are digging into how intelligence agencies target Americans. Plans include a new panel to examine the weaponization of the federal government against U.S. citizens.

New information about the FBI's work with other federal agencies and state and local officials is included in the 906-page rule book authored during the Trump administration and revised under President Biden. The bureau published the updated Domestic Investigations and Operations Guide online after rejecting requests to make it public.
