“Not even during the Civil War did insurrectionists breach our Capitol, the citadel of our democracy,” Mr. Biden said in his statement. “But six months ago today, insurrectionists did.” The president said the riot had “posed an existential crisis and a test of whether our democracy could survive.” “While it shocked and saddened the nation and the world, six months later, we can say unequivocally that democracy did prevail — and that we must all continue the work to protect and preserve it,” he said. In addition to condemning the actions of the rioters, Mr. Biden honored the members of the United States Capitol Police who died during or after the attack.
