Obituary for a Failed Presidency | The New Yorker:
…the stalking menace of these past few years. As Trump became more powerful and less constrained by successive waves of White House advisers, he was correspondingly more and more outrageous, untruthful, and unmoored from reality. His sense of grievance and victimization escalated; so, too, did his threats, name-calling, and public provocations. He fired the F.B.I. director, a Secretary of State, an Attorney General, a Defense Secretary, three White House chiefs of staff, and two—or three, depending on whose account you believe—national-security advisers. He pardoned war criminals and boasted of complete and total vindication in the Mueller investigation, even though it offered no such thing. He forced the longest government shutdown in history when Congress would not fund his border wall—all while continuing to claim that Mexico would pay for it.
