Trump's remarks were vague, so it's unclear precisely how tuned in he is to the full scope of QAnon's worldview. He addressed the broad outlines of the theory and his perceived role in it.
"Well I don't know much about the movement, other than I understand they like me very much -- which I appreciate," he said. He also said "I’ve heard these are people that love our country."
A reporter asked him specifically about "this belief that you are secretly saving the world from this satanic cult of pedophiles and cannibals. Does that sound like something you are behind or a believer in?"
"Well, I haven’t ... heard that," Trump replied. "But is that supposed to be a bad thing or a good thing? I mean, you know, if I can help save the world from problems, I’m willing to do it. I’m willing to put myself out there."
Trump tweeted congratulations last week to a Republican congressional primary winner from Georgia who has promoted QAnon theories in the past and who may be headed for Congress next year but declined on Friday to acknowledge a reporter's questions about QAnon.
Fellow Republicans were quick to weigh in. "Why in the world would the President not kick Q’anon supporters’ butts? Nut jobs, rascists [sic], haters have no place in either Party," Former Florida Gov. Jeb Bush tweeted.
The QAnon phenomenon appears to be growing with alarming speed and dexterity through America’s social media landscape in recent months, with a 71% increase in content on Twitter and 651% growth in Facebook pages and groups since March, according to researcher Marc-André Argentino, a PhD candidate at Concordia University in Montreal, Canada who studies the nexus between technology and extremist groups.
While shadowy internet groups have grown adept at sidestepping platform restrictions by adopting new names and hashtags, researchers can still track identifiable content affiliated with QAnon because most of it has only recently been restricted. From what is thought to be its genesis in 2017 to March 2020, QAnon -- which imagines Trump working in secret against a global cabal of pedophiles -- grew to more than 220,000 members of QAnon-related Facebook groups, according to Argentino's research. Since March, it has swelled to at least 1.7 million members.
People who believe in QAnon conspiracies have also been associated with a number of bizarre real-life incidents in recent years, including a man using an armored truck to block traffic on the Hoover Dam in 2018. When authorities arrived the man was standing next to his vehicle with a sign unfurled to reveal a popular QAnon rallying cry.
From jail, the man wrote a letter ending with the phrase "For where we go one, we go all," according to the Associated Press -- a phrase used commonly on QAnon forums and conspiracy theory websites.
A man accused of fatally shooting alleged Gambino mob boss Francesco "Franky Boy" Cali last year believed Cali was part of the "deep state," according to court records.
Anthony Commello's defense attorney said in court documents that, based on interviews with the alleged shooter's family, his client "became increasingly vocal about his support for QAnon," about six weeks before Cali's murder. "But [his] support for QAnon went beyond mere participation in a radical political organization, it evolved into a delusional obsession ... He ardently believed that [Cali] was a prominent member of the Deep State, and, accordingly, an appropriate target for a citizen's arrest."
Commello has pleaded not guilty by reason of insanity and his trial is pending.
'Militant and anti-establishment ideology'
In a declassified internal memo last year, the FBI declared conspiracy theory movements like QAnon potential domestic terror threats, and last month the Combating Terror Center at the U.S. Military Academy in West Point published a research paper which asserts that QAnon "represents a militant and anti-establishment ideology [which] finds resonance with other far-right extremist movements.”
Yet experts said that only when QAnon began joyriding through mainstream cyberspace this summer -- commandeering legitimate issues and smearing random retailers and celebrities by falsely tying them to a fictitious international child sex trafficking ring -- did major social media platforms like Twitter, Facebook, YouTube and TikTok begin to take action to thwart its spread.
On Wednesday, Facebook announced that it was removing 790 groups, 100 pages and 1,500 ads related to QAnon, following similar actions Facebook and others have taken earlier this month.
"We have seen growing movements that, while not directly organizing violence, have celebrated violent acts, shown that they have weapons and suggest they will use them, or have individual followers with patterns of violent behavior,” the company said in a statement.
Some experts think recent actions by the big social media giants may be too little, too late.
"I assumed that once it became obvious that this was a serious problem, that the intervention would come,” said Travis View, co-host of the QAnon Anonymous podcast, which employs a satirical format to track and report on the group’s progress online and in real life.
View said that the big social platforms should have moved sooner. He pointed to Reddit's banning of QAnon subreddits from its site in 2018 over violent threats and targeted harassment.
"So they recognized that it was a problem a lot sooner than every other social media platforms [which] have had to take some sort of action these past couple of weeks.”
"But what sort of surprised me isn't the growth of the community, but the lack of action from the people who might be able to do something about it," View said. "The tolerance for the growth of QAnon from powerful, influential people is what surprised me more than anything else.”
Last month, the MIT Technology Review published a grim report, titled 'It’s too late to stop QAnon with fact checks and account bans', by senior editor Abby Ohlheiser, a former Washington Post reporter who focuses on internet culture.
"When I talked to researchers for my story about this question -- whether it’s too late -- I heard two responses,” Ohlheiser told ABC News last week. "First, that platforms have housed QAnon activity relatively unfettered there for nearly three years, giving it a pretty significant head start."
Ohlheiser said the second conclusion researchers reached was more chilling: that the faceless culture of pseudonymous online hate and disinformation has so deeply infested the social media ecosystem -- to the point where it can disrupt commerce, hijack nonprofits and virally spread damaging disinformation -- that the system itself may need to be rebuilt, or at least reimagined.
The second group of researchers told her "that while things like fact checks and account bans can help address misinformation and bad actors on these platforms, that at this point, a much more dramatic rethinking of the information ecosystem is needed to effectively address what QAnon and conspiracy-fueled misinformation has become over time.”
Still, some experts who study conspiracy theories suggested this week that fears about the group's growth are overblown. "In short, support for QAnon appears to be deeper than it is wide," two political scientists who have been polling Americans on QAnon in recent years wrote in The Guardian on Wednesday. As the authors point out, a March 2020 Pew Research poll found that 76% of Americans knew nothing about QAnon, 20% knew a little, and only 3% knew a lot.
In March, Oprah Winfrey publicly disputed false claims posted online by QAnon devotees. At the same time a prominent Hollywood couple had been the target of a vicious and extensive trolling campaign by QAnon adherents.
Last month, QAnon followers set their sights on a prominent U.S. furniture retailer by flooding the internet with an outrageous conspiracy theory. Soon, the outlet's name started trending on Twitter, and then on Instagram, and then on TikTok -- before administrators could disable the trending hashtags.
Earlier this month, QAnon conspiracy theorists co-opted the #SaveTheChildren campaign -- sending posts surging, while mixing in pro-Trump QAnon theories to win new adherents. QAnon followers flooded the nonprofit National Human Trafficking Hotline with phone calls, straining resources needed to track real missing children.
The conspiracy theory may also help land a representative in the halls of Congress with Marjorie Taylor Greene, a political novice and candidate from Georgia, poised to win an open House seat there.
There are currently 20 candidates -- 19 Republicans and one independent -- who have "have endorsed or given credence to the conspiracy theory" that have secured a spot on the ballot in the 2020 congressional elections, according to the media watchdog Media Matters.
So how did we get here and what happens next?
What is QAnon?
QAnon, which dates back to 2017 but has its roots in the 2016 Pizzagate scandal, centers around a conspiracy theory about a secret cabal of Satan-worshipping pedophile power players that control Hollywood, much of the media and key levers of the federal government -- and that only Trump and a secret "Q team” of top military and intelligence officials working in the shadows have the power to stop them, according to researchers and experts who spoke to ABC News.
In 2016, a North Carolina man drove to a Washington D.C. and entered a pizza restaurant with a firearm to investigate a child-sex trafficking conspiracy theory that had been peddled on numerous websites and shared on social media accounts. He opened fire on a locked closet door before surrendering to police. He pleaded guilty to weapons charges in 2017 and is serving four years in prison.
"Q" is purported to be a high-level government official with access to classified intelligence and the leader of the secret movement to thwart the pedophile ring. The "Q” handle first posted on a 4chan imageboard in October 2017, with a cryptic message suggesting that Hillary Clinton was about to be taken into custody for her role in the imagined conspiracy -- one of numerous predictions that have failed to materialize inside or outside the QAnon universe.
Since then, the "Q” handle and its offshoots have posted scores more "Q drop” messages on a succession of platforms: 4chan, 8chan and 8kun. The phenomenon fuses aspects of gaming, religion and puzzles, according to experts and researchers. Believers post videos in which they claim Trump is secretly flashing them a "Q” sign.
"He doesn’t tell you what to think -- he leads you to information,” QAnon enthusiast David Buffamoyer told ABC News' David Wright after appearing at a 2018 Trump rally in Wilkes-Barre, Pennsylvania, in clothing associated with QAnon. "You can read it and decide for yourself what you think. That’s the 'bread crumbs' [and] you follow them.”
Followers anticipate two game-changing events -- The Storm and The Great Awakening. The Storm -- for QAnon believers -- is the anticipated mass arrests of tens of thousands of powerful elites in Hollywood, media, business and politics.
The Great Awakening is the day when everyone realizes "Q” was right all along, and society is finally ready to advance into a utopian future, experts said.
"It gives them a feeling of control,” said Kathryn Olmsted, a University of California, Davis history professor who studies the impact of conspiracy theories on American politics. "They believe they are losing power to people they define as un-American. And that believing in this theory gives them power and control that otherwise they have lost. If Donald Trump is orchestrating or being helped by this conspiracy, then all of the bad people will be exposed and the country will be saved -- [and] then they can be part of a very important movement, they can play a role in history by being a member of the movement.”
Prior to Trump's remarks on Wednesday, White House Press Secretary Kayleigh McEnany was asked at a briefing if she's ever heard Trump talk about QAnon, and what the president thinks of the conspiracy theory.
"I've never heard of that. There's a lot of media focus on that, but certainly never heard of that from the president," McEnany said.
