Twitter has shut down multiple accounts that it says were operated by a white supremacist group posing as liberal groups encouraging violence.
Twitter said the white supremacist group Identity Evropa used one fake account, @Antifa_US, to call for violence in majority white suburbs, in the name of the Black Lives Matter movement. The account's removal was first reported by NBC News.
An Identity Evropa account purported to be associated with Antifa, a collection of loosely connected groups that organize against fascism. On Sunday, Attorney General William Barr said Antifa was associated with violence at recent protests. Officials have yet to show evidence to support this claim.
Without identifying any particular group, a May 31 Department of Homeland Security note warned that well-coordinated groups had "potentially compromised" law enforcement radio communications in Portland, Oregon over the weekend. The note warned that those seeking to incite violence in other locations could be "monitoring local law enforcement communications to identify vulnerabilities in their operational security posture."
