"Thank you very much, Chairman Thompson. Thank you to all of my colleagues on this committee, and thank you to each of the witnesses appearing before us today. It is because of you -- you held the line, you defended all of us, you defended the Capitol, and you defended the Constitution and our Republic, and every American owes you our undying gratitude. Every American, I hope, will be able to hear your testimony today and will watch the videos. The videos show the unbelievable violence and the inexcusable and intolerable cruelty that you all faced, and people need to know the truth."
Rep. Liz Cheney (R-WY) sharply criticized Rep. Elise Stefanik (R-NY) for blaming Speaker Nancy Pelosi for the January 6th insurrection.
