A May 30, 2019, FBI "Intelligence Bulletin" memo from the Phoenix Field Office identified QAnon-driven extremists as a domestic terrorism threat. The document cited a number of arrests related to QAnon, some of which had not been publicized before.[173] According to the memo, "This is the first FBI product examining the threat from conspiracy theory-driven domestic extremists and provides a baseline for future intelligence products. ... The FBI assesses these conspiracy theories very likely will emerge, spread, and evolve in the modern information marketplace, occasionally driving both groups and individual extremists to carry out criminal or violent acts."[173][174]
According to FBI's counterterrorism director Michael G. McGarrity's testimony before Congress in May, the FBI divides domestic terrorism threats into four primary categories, "racially motivated violent extremism, anti-government/anti-authority extremism, animal rights/environmental extremism, and abortion extremism," which includes both pro-choice and anti-abortion extremists. The fringe conspiracy theory threat is closely related to the anti-government/anti-authority subject area.[173][174]
An under-reported QAnon-related incident was mentioned in the memo: the December 19, 2018, arrest of a California man whose car contained bomb-making materials he intended to use to "blow up a satanic temple monument" in the Springfield, Illinois, Capitol rotunda to "make Americans aware of Pizzagate and the New World Order, who were dismantling society." According to the same source, the FBI said another factor driving the intensity of this threat is "the uncovering of real conspiracies or cover-ups involving illegal, harmful, or unconstitutional activities by government officials or leading political figures."[173]
QAnon followers' reactions included the suggestion the memo was fake, calling for the firing of FBI director Christopher A. Wray for working against Trump, and the idea that the memo was actually a "wink-and-a-nod" way of attracting attention to QAnon and tricking the media into asking Trump about it.[175] At a Trump reelection rally several hours after the memo's existence became known, WalkAway campaign founder Brandon Straka, a gay man who claims to have been a liberal Democrat but is now a Trump supporter, addressed the crowd using one of QAnon's primary rallying cries, "Where we go one, we go all". A videographer found numerous QAnon supporters in the crowd, identified by their QAnon shirts showing large "Q"'s or "WWG1WGA".[36]
