"Mr. Trump sparked these assaults. He has railed for months against the verdict rendered by voters in November.
He summoned his supporters to gather in Washington on this day, and encouraged them to march on the Capitol. He told them that the election was being stolen. He told them to fight. He told them he might join them and, even as they stormed the building, he declined for long hours to tell them to stop, to condemn their actions, to raise a finger in defense of the Constitution that he swore to preserve and protect. When he finally spoke, late in the day, he affirmed the protesters’ anger, telling them again that the election was stolen, but asking them to go home anyway. It was the performance of a man unwilling to fulfill his duties as president or to confront the consequences of his own behavior."
