Donald Trump assassination attempt: Fact-checking some online rumours

Misinformation and conspiracy theories were spreading online after an assassination attempt on former US President Donald Trump at a campaign rally on Saturday.

Thomas Matthew Crooks, 20, was alleged to have shot at the Republican presidential candidate from a rooftop during the rally in Butler, Pennsylvania, wounding Trump's right ear. One spectator died and two others were injured.

Reuters has fact-checked some of the most widely shared narratives online.

Misidentified shooters

Within hours of the shooting, an image surfaced online of a man dressed in a black sweatshirt, hat and black sunglasses. Social media posts said the man was “Antifa extremist” Mark Violets and that he was named by local police as the suspect in the assassination attempt.

However, the man in the photograph is Marco Violi, who had nothing to do with the shooting. Violi is an Italian sports writer who shares content on the Italian soccer team AS Roma.

In a statement emailed to Reuters and shared on his social media, Violi said he was in Rome and had awoken at 2 a.m. to numerous messages, adding that he “categorically denied any involvement in the situation.”

Violi was not the only individual to have been misidentified in the immediate aftermath of the shooting.

Viral posts also misidentified another man, Maxwell Yearick, as the shooter. In 2016, various media outlets reported that Yearick, who does not resemble Crooks, was arrested outside a Pittsburgh Trump rally after an altercation with police.

Altered images, false claims shooting was staged

Doctored images of Trump and Secret Service agents smiling on stage surfaced in the immediate aftermath of the shooting. The fake images were shared to support claims that the assassination attempt had been “staged” as a ploy to boost Trump’s popularity in November’s election.

The original photographs were captured by an Associated Press photographer and show Trump and the agents with serious facial expressions.

The FBI on Sunday said Crooks acted alone and the agency had yet to identify a motive.

Predictive programming conspiracy theories

Predictive programming is a conspiracy theory, often revived in the aftermath of a major news event, that suggests governments and powerful groups provide indications of planned events to the public by embedding predictions in books, TV shows and movies.

Within an hour of the attempted assassination, a fabricated screenshot resurfaced of a cartoon of Trump in a casket and was described as a scene from the TV series The Simpsons.

But this image has made the rounds on social media since at least 2017.

Matt Selman, an executive producer for the show, told Reuters in an email that the screenshot never appeared on the show, adding that it is “all too easy to create fake Simpsons ‘predictions’ like these for the purpose of misleading people.”

A spokesperson for Trump did not immediately respond to a request for comment.
