False rumors that antifa is organizing bus rides to take protesters into white neighborhoods and loot homes have gone viral in recent days on digital neighborhood platforms and in group texts throughout the U.S. Some of the posts feature a screenshot of a tweet by a fake antifa Twitter account that Twitter said was created by the white nationalist group Identity Evropa, attempting to drum up fear of looting in residential and suburban areas. On Tuesday, Facebook added a warning to posts on Facebook and Instagram indicating that the fake antifa post was "false information." By then, the post had already gone viral on both platforms, generating hundreds of thousands of interactions. The post was shared by pro-Second Amendment and conservative media pages like Red State and Hot Air. It was also shared by "U.S. Law Enforcement," a page with nearly a half-million followers that claims to be "run by several current and retired U.S. law enforcement officers," which posted the screenshot of the tweet and wrote: "Antifa is warning that tonight they're moving out of the cities - and into residential areas to 'take what's ours.' Law enforcement across the country on high alert. Circulate this asap." The post was also widely shared on Instagram, led by Trump Jr., who shared the post Sunday and wrote: "Absolutely insane. Just remember what ANTIFA really is. A Terrorist Organization! They're not even pretending anymore." His post was liked 96,000 times. Trump Jr. ... deleted the post Tuesday morning.
