evidence: The claim: A video shows antifa inside the Capitol building with floor plans and dressed as Trump supporters on Jan. 6, proving the attack was a setup [...] Based on our research, we rate FALSE the claim that a video shows antifa inside the Capitol building with floor plans and dressed as Trump supporters on Jan. 6, proving the attack was a setup. Experts said antifa was not involved in the Jan. 6 attack, and all evidence indicates that a pro-Trump mob was responsible for breaking into the Capitol building. Some of the rioters in the video are well-known Trump supporters. In addition, the footage does not prove that the attack was a setup. It shows events that occurred when the attack was underway.
