President Trump tweeted Friday that he "can't stand back" and watch as protests in Minneapolis against the police killing of George Floyd bleed into looting and arson. Trump threatened to send in the National Guard, which Gov. Tim Walz (D) had activated Thursday, adding: "These THUGS are dishonoring the memory of George Floyd, and I won't let that happen. ... Any difficulty and we will assume control but, when the looting starts, the shooting starts. Thank you!" Twitter added a warning to that second tweet stating it "violated the Twitter Rules about glorifying violence," but left it up because "it may be in the public's interest for the tweet to remain accessible." The official White House Twitter account later quoted and posted the tweet. Trump signed an executive order on Thursday "challenging the liability protections that have served as a bedrock for unfettered speech on the internet," The Associated Press writes. The move comes after Twitter labeled two of Trump's tweets on mail-in ballots as misleading.
