One thing you have to know about Trump. He’s like an orange-topped mollusk. He moves uninvited from place to place, spreading a wide trail of ooze, and then he moves on, leaving a stain that, try as you might, you just can’t get out.

He left a stain in New York, when he tore down the old Bonwit Teller building, at Fifth Avenue and 56th St.—a limestone gem designed by Warren and Wetmore. This was where he constructed his gaudy, gold, intromittent-organ replacement, Trump Tower.
