COLUMBUS, Ohio — The reports of hateful and violent posts on Facebook started pouring in on the night of May 28 last year, soon after then-President Donald Trump sent a warning on social media that looters in Minneapolis would be shot.

It had been three days since Minneapolis police officer Derek Chauvin kneeled on the neck of George Floyd for more than eight minutes until the 46-year- Black man lost consciousness, showing no signs of life. A video taken by a bystander had been viewed millions of times online. Protests had taken over Minnesota’s largest city and would soon spread throughout cities across America.

But it wasn't until after Trump posted about Floyd’s death that the reports of violence and hate speech increased “rapidly” on Facebook across the country, an internal company analysis of the ex-president’s social media post reveals.

“These THUGS are dishonoring the memory of George Floyd and I won’t let that happen,” Trump tweeted at 9:53 p.m. on May 28, in comments he repeated on his Facebook account a few hours later. “Any difficulty and we will assume control but, when the looting starts the shooting starts!”

The former president has since been suspended from both Twitter and Facebook.

Leaked Facebook documents provide a first-hand look at how Trump’s social media posts ignited more anger in an already deeply divided country that was eventually lit “on fire” with reports of hate speech and violence across the platform. Facebook’s own internal, automated controls, meant to catch posts that violate rules, predicted with almost 90% certainty that Trump's message broke the tech company's rules against inciting violence..

Offline, the next day, protests — some of which turned violent — engulfed nearly every U.S. city, big and .

“When people look back at the role Facebook played, they won’t say Facebook caused it, but Facebook was certainly the megaphone," said Lanier Holt, a communications professor at Ohio State University. “I don’t think there’s any way they can get out of saying that they exacerbated the situation."

Facebook’s internal discussions were revealed in disclosures made to the Securities and Exchange Commission and provided to Congress in redacted form by former Facebook employee-turned-whistleblower Frances Haugen’s legal counsel. The redacted versions received by Congress were obtained by a consortium of news organizations, including The Associated Press.

The Wall Street Journal previously reported that Trump was one of many high-profile users, including politicians and celebrities, exempted from some or all of the company’s normal enforcement policies.

Hate speech and violence reports had been mostly limited to the Minneapolis region after Floyd's death, the documents reveal.

The internal analysis shows a five-fold increase in violence reports on Facebook, while complaints of hate speech tripled in the days following Trump's post. Reports of false news on the platform doubled. Reshares of Trump's message generated a “substantial amount of hateful and violent comments," many of which Facebook worked to remove. Some of those comments included calls to “start shooting these thugs” and “f—- the white."

By June 2, “we can see clearly that the entire country was basically ‘on fire,’” a Facebook employee wrote of the increase in hate speech and violence reports in the June 5 memo.

Facebook says it's impossible to separate how many of the hate speech reports were driven by Trump's post itself or the controversy over Floyd's death.

“This spike in user reports resulted from a critical moment in history for the racial justice movement — not from a single Donald Trump post about it," a Facebook spokesperson said in a statement. “Facebook often reflects what’s happening in society and the only way to prevent spikes in user reports during these moments is to not allow them to be discussed on our platform at all, which is something we would never do.”

That contradicts conversations Zuckerberg had with civil rights leaders last year to quell concerns that Trump's post was a specific threat to Black people protesting Floyd's death, said Rashad Robinson, the president of Color of Change, a civil rights advocacy group. The group also spearheaded a boycott of Facebook in the weeks following Trump's post.

“To be clear, I had a direct argument with Zuckerberg days after that post where he gaslit me and he specifically pushed back on any notion that this violated their rules,” Robinson said in an interview with the AP last week.

A Facebook spokesperson said that its internal controls do not always correctly predict when a post has violated rules and that human review, which was done in the case of Trump's post, is more accurate.

To curb the ex-president's ability to stoke hateful reactions on its platform, Facebook employees suggested last year that the company limit reshares on similar posts that may violate Facebook's rules in the future.

But Trump continued to use his Facebook account, which more than 32 million follow, to fire up his supporters throughout much of the remainder of his presidency. In the days leading up to a deadly siege in Washington on Jan. 6, Trump regularly promoted false claims that widespread voter fraud caused him to lose the White House, spurring hundreds of his fans to storm the U.S. Capitol and demand the results of a fair election be overturned.

It wasn't until after the Capitol riot, and as Trump was on his way out of the White House, that Facebook pulled him off the platform in January, announcing his account would be suspended until at least 2023.

There's a reason Facebook waited so long to take any action, said Jennifer Mercieca, a professor at Texas A&M University who closely studied the former president's rhetoric.

"Facebook really benefited from Trump and Trump’s ability to draw attention and engagement through outrage," Mercieca said. "They wanted Trump to keep going on."
