evidence: The Jan. 6, 2021, attack on the U.S. Capitol was not a "setup" by antifa activists who were "already inside the Capitol with floor plans dressed as Trump supporters." The viral Facebook post making that claim revived a debunked conspiracy theory. A University of Chicago research group that has examined 900 people charged to date has found no evidence of antifa involvement in the day's events. A video captured amid the attack does not show antifa; it shows a group of pro-Trump rioters, including some whose support for former President Donald Trump has been documented in charging documents, discussing the Capitol’s layout after breaching it.
