President Donald Trump posted a message on his Twitter account today that tagged a pro-QAnon account.

On Tuesday, Trump posted a message to Twitter advocating for the passage of voter identification laws “to insure the safety and sanctity of our voting system.” Aside from the typo, Trump tagged an account that has shared images supportive of the QAnon phenomenon, which hinges on a conspiracy theory alleging that Trump and other administration officials are working behind the scenes to dismantle an international network of satanic pedophiles that includes top-ranking Democrats. Those who believe in the conspiracy theory think that a Trump administration official with high-level security clearance is posting riddles on 8chan that, once decoded, contain details about the supposed plan.

We should immediately pass Voter ID @Voteridplease to insure the safety and sanctity of our voting system. Also, Paper Ballots as backup (old fashioned but true!). Thank you! — Donald J. Trump (@realDonaldTrump) July 30, 2019

The account that Trump tagged has an image banner on its profile presenting the slogan “Where We Go One We Go All,” a catchphrase popular in pro-QAnon circles. In its user bio, the account displays the same message in anagram form: “WWG1WGA.” A brief review of the profile shows numerous pro-QAnon postings.

Trump has injected pro-QAnon Twitter users into the public ether multiple times before. In March, Trump retweeted a video from an account called Deep State Exposed. Trump retweeted the same account two months later. Last year, Trump posed for a photo in the Oval Office with a pro-QAnon YouTube broadcaster, and earlier this month Trump invited right-wing social media stars, including at least two that are supportive of QAnon, to the White House for face time with the administration.

QAnon followers have been arrested for bizarre and violent actions that were motivated in part by their belief in the conspiracy theory. The lawyer for a 24-year-old suspect accused of murdering a New York mob boss earlier this year stated that the suspect’s belief in QAnon contributed to the situation in which he shot and killed the victim.
