In addition, nearly 300 state legislators from battleground states reportedly participated in a private briefing with Trump, attorneys Rudy Giuliani and John Eastman, and others, on Jan. 2, in which Trump reportedly urged them to exercise what he called "the real power" to choose electoral votes before Jan. 6, because, said Trump on the call, "I don't think the country is going to take it," the report said.The committee also reported that, in the year leading up to the Jan. 6 attack, there were at least nine incidents in which far-right protesters entered state capitols, and that at least four of these capitol incursions -- in Michigan, Idaho, Arizona, and Oregon -- involved identifiable individuals who later participated in the attack on the U.S. Capitol.Among those witnesses whose testimony was released were former President Donald Trump's one-time national security adviser Michael Flynn, Proud Boys leader Enrique Tarrio, Oath Keepers leader Stewart Rhodes, Infowars host Alex Jones, onetime Trump campaign adviser Roger Stone, and Trump-backed attorneys John Eastman and Jenna Ellis.The committee also said at least four sitting Republican members of Congress would be referred to the House Ethics Committee for "appropriate sanction," including House Minority Leader Kevin McCarthy, Rep Jim Jordan, R-Ohio, Rep Scott Perry, R-PA, and Rep Andy Biggs, R-Ariz.Trump has dismissed the work of the committee, mocking it as the "Unselect Committee" and calling it a "political Witch Hunt."ABC News' Soo Rin Kim, Lauren Peller, Allison Pecorin, Lucien Bruggeman, Hannah Demissie, Luke Barr, Will McDuffie, Beatrice Peterson, Mike Levine, Alexander Mallin and John Santucci contributed to this report."
