The report is the product of a months-long investigation by the Senate Rules and Administration and the Homeland Security and Governmental Affairs committees.

It concludes the Capitol Police’s main intelligence component, the Intelligence and Interagency Coordination Division (IICD), was “aware of the potential for violence in the days and weeks ahead of January 6.”

The IICD upped its warning about the possibility of an attack from “remote” to “improbable” in the days leading up to the riot, but the Capitol Police did not order a department wide operational security plan for January 6.

The FBI and DHS, meanwhile, did not disseminate any formal intelligence warnings about threat posed on January 6, as agencies did not deem “online posts calling for violence at the Capitol as credible.”

The report also concluded Capitol Police officers were not provided sufficient training in “basic civil disturbance tactics” and the agency’s command system “broke down during the attack,” leaving front line law enforcement without sufficient instruction during the riot.

“Opaque processes and a lack of emergency authority delayed” requests by the Capitol Police for National Guard assistance, the report concluded.
