Mr. Trump’s ruinous tenure already has gravely damaged the United States at home and around the world. He has abused the power of his office and denied the legitimacy of his political opponents, shattering the norms that have bound the nation together for generations. He has subsumed the public interest to the profitability of his business and political interests. He has shown a breathtaking disregard for the lives and liberties of Americans. He is a man unworthy of the office he holds.
