Twitter put a warning label on a tweet by President Donald Trump about the Minneapolis protests early on Friday, saying that it violated the company’s rules about "glorifying violence."
The social network did not remove the tweet, instead letting users click on a link next to the label to view it.
The tweet, the second in a two-part thread from the president, said that during the protests sparked by the death of George Floyd, "when the looting starts, the shooting starts."
Floyd’s death, which came after a police officer crushed his neck under his knee while arresting him, has led to violent protests in Minneapolis this week. On Thursday night, protesters clashed with officers in the area and set a police building on fire.
The phrase "when the looting starts, the shooting starts" has a history. In 1967, Miami Police Chief Walter Headley used it to describe his approach to protests in black neighborhoods.
