(Reuters) - Twitter hid a tweet by U.S. President Donald Trump behind a warning for the first time on Friday, accusing him of breaking its rules by "glorifying violence" in a message that said looters at protests in Minneapolis would be shot.
Twitter's decision to step in escalates a feud between Trump and tech companies. It came hours after Trump signed an executive order threatening Silicon Valley social media firms with new free speech regulations, amid a fight with Twitter after the company added a fact-checking tag to his tweets this week about unsubstantiated claims of fraud in mail-in voting.
It also comes at a time of racially-charged civil unrest in cities across the United States over the death of George Floyd, a black man seen on video gasping for breath while a white police officer knelt on his neck.
Trump's tweet labeled by Twitter read: "...These THUGS are dishonoring the memory of George Floyd, and I won’t let that happen. Just spoke to Governor Tim Walz and told him that the Military is with him all the way. Any difficulty and we will assume control but, when the looting starts, the shooting starts. Thank you!"
The official White House Twitter account also later sent out the same message. Twitter declined to comment on whether it would be taking the same action on the new tweet.
Trump, who has more than 80 million followers on Twitter, responded by accusing the company of targeting him, Republicans and other conservatives for censorship. He threatened to impose new regulation on internet companies and called on Congress to revoke a law, known as Section 230, that protects online platforms from lawsuits over content.
Trump's message can now be seen only after clicking on a notice which says: "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."
A Twitter spokeswoman said CEO Jack Dorsey had been informed of the decision to tag Trump's tweet before the label was applied. The decision was based on a policy introduced in June, 2019, which the company said it had applied previously, pointing to a tweet by a Brazilian cabinet member in April this year.
Trump issued his tweet amid days of unrest in Minneapolis, which was engulfed in a third night of arson, looting and vandalism as protesters vented their rage over Floyd's death.
Trump has condemned the killing of Floyd and promised justice. Four police officers involved in Floyd's death have been fired and the FBI is investigating.
UNREST IN MINNEAPOLIS, LOUISVILLE
Floyd's death was one of several killings of black people in the United States in recent months that has provoked outrage. The Minneapolis night sky was lit up with flame from a police precinct that had been torched overnight.
In the morning, riot police in gas masks arrested a CNN crew on live TV, leading them away in handcuffs from streets that resembled a war zone. More than an hour later, the crew was released.
Protests took place in other U.S. cities including Louisville, Kentucky, where police said seven people were shot. Protesters there vented rage over the police killing of Breonna Taylor, a black woman shot in her apartment in March.
Twitter said it acted over the Trump tweet "in the interest of preventing others from being inspired to commit violent acts". People will still "be able to retweet with comment, but will not be able to like, reply or retweet it".
Facebook did not remove President Trump's same post from its site, where it had 34,000 shares. A company spokesman declined to comment on whether the post violated its rules about content that incites or threatens violence.
Facebook chief executive Mark Zuckerberg, in TV interviews aired on Thursday, took pains to distance his company, which also exempts politicians from its third-party fact-checking program, from Trump's dispute with Twitter.
