Twitter "hid" a tweet by President Donald Trump on Friday morning, saying that the message violated the platform's rules about "glorifying violence."

The tweet was in reference to protests in Minneapolis regarding the death of George Floyd. Trump threatened to send in the National Guard if Minnesota officials could not reign in rioting and added that "when the looting starts, the shooting starts." He also refered to looters as "THUGS."

According to

NBC News,

the phrase, "when the looting starts, the shooting starts" has some historical context. It was first used in 1967 Miami's police chief Walter Headley, who used the phrase in connection with racial minorities in the city. The quote was said to contribute to race riots in the city in the late '60s.

Trump's tweet is now no longer visible directly from his timeline. Instead, the tweet is covered up by a message.

"This Tweet violated the Twitter Rules about glorifying violence. However, Twitter has determined that it may be in the public's interest for the Tweet to remain accessible," the message read.

It appears to be the first time Twitter has chosen to hide — but not delete — a tweet from Trump that violates the site's terms of service. Previously, Twitter had chosen not to do anything to Trump's tweets that violated its terms of service.

The move came hours after Trump signed an

executive order

that he said was designed to regulate what he considers to be "anti-conservative" bias in social media. Trump's order was in response to Twitter applying a fact-check link to two of his tweets about mail-in voting, which led users to more information on the subject.

On Friday morning, the White House Twitter account tweeted the same message that Trump had tweeted. A little over an hour later, Twitter chose to hide that tweet as well.

Facebook, YouTube and Twitter have removed posts from President Donald Trump on Wednesday as some of his supporters violently entered the US Capitol on Wednesday.

Meanwhile, Twitter said that Trump's account will be locked for at least 12 hours.

While Trump has been angered by Twitter for flagging his tweets in the past, Twitter has not previously deleted the president's tweets to preserve his posts for public record. But given the violence in DC, Trump’s tweets were removed.

Among the tweets deleted was a video sent to supporters telling them to “go home.” The video, however, once again made false claims that the 2020 presidential election was stolen.

All told, three Twitter posts were deleted.

The video was also deleted from Facebook and YouTube.

Guy Rosen, the vice president of integrity at Facebook, said in a tweet the social media site was removing the video because "on balance we believe it contributes to rather than diminishes the risk of ongoing violence."

Facebook later stated that Trump's account will be locked for 24 hours.

"We've assessed two policy violations against President Trump's Page which will result in a 24-hour feature block, meaning he will lose the ability to post on the platform during that time," Facebook said.

Twitter also released a statement.

"In regard to the ongoing situation in Washington, D.C., we are working proactively to protect the health of the public conversation occurring on the service and will take action on any content that violates the Twitter Rules," Twitter tweeted. "In addition, we have been significantly restricting engagement with Tweets labeled under our Civic Integrity Policy due to the risk of violence. This means these labeled Tweets will not be able to be replied to, Retweeted, or liked."
