A security bulletin, along with other reports on protests, was compiled by the department’s Federal Protective Service (FPS) a day before the attack and warned that anti-government and racially motivated extremists were likely to participate in the rally near the White House and “use the activities as an opportunity to promote their ideologies and motivate followers to promote violence.”…
The bulletin lists the Internet addresses for more than 30 Facebook groups that the FPS appeared to be aware of, from “March on Congress” to “Trumps MAGA Rally Stop the Steal” to “Fight for Trump Washington DC — 01/06/2021.”
Other Facebook groups were specific to convoys of buses being organized from New Jersey and Ohio. The bulletin shows that the FPS calculated the number of “committed” attendees from each Facebook group and a larger number of people who were “interested” in the events of Jan. 6.
Combined with a second list of Facebook groups in another email, the documents reveal that agents were drawing on information from nearly three dozen social media forums, most ostensibly organized by Trump supporters
