The 15-page document was filed May 30, 2019 from the bureau's Phoenix office. It describes "conspiracy theory-driven domestic extremists" as a growing threat and notes that it is the first such report to do so.

"The FBI assesses these conspiracy theories very likely will emerge, spread, and evolve in the modern information marketplace, occasionally driving both groups (QAnon and Pizzagate) and individual extremists to carry out criminal or violent acts."

The report focuses primarily on ideeological motivations. Last week, FBI Director Wray asserted that the FBI is concerned only with violence, not people's beliefs, stating The FBI doesn't "investigate ideology, no matter how repugnant. We investigate violence, we are all over it."

Michael German, a former FBI agent and now a fellow with the Brennan Center for Justice's Liberty & National Security program doesn't think so. He stated: "It's part of the radicalization theory the FBI has promoted despite empirical studies that show it's bogus. German claims this new category is a continuing part of FBI overreach, stating, "They like the radicalization theory because it justifies mass surveillance. If we know everyone who will do harm is coming from this particular community, mass surveillance is important."
