evidence: On Jan. 6, 2021, supporters of outgoing U.S. President Donald Trump violently converged on the U.S. Capitol in Washington, D.C. in support of Trump's false claims that the November 2020 presidential election was beset by massive scale voter fraud that led to his loss. [...] Some right wing figures pointed to John Sullivan, an accused agent provocateur who filmed the death of Ashli Babbitt, an Air Force veteran and Trump supporter who was shot by police when she tried to break through a barricaded door as rioters broke into the building. Sullivan was arrested in Utah on Jan. 14, 2021, on charges related to the riot. [...] The FBI said during a Jan. 8, 2021, news conference that there was "no indication" that anyone from the antifa movement was involved in the attack. House Minority Leader Kevin McCarthy, a California Republican who has been an outspoken Trump supporter, bluntly rejected the claim that the riot was instigated by left wing activists, stating, "Some say the riots were caused by antifa. There is absolutely no evidence of that. And conservatives should be the first to say so."
