Five years ago, on March 31, 2016, when Trump was on the verge of winning the Republican presidential, we worked together for the first time and interviewed Trump as his then unfinished Trump International Hotel on Pennsylvania Avenue in Washington. That day we recognized he was an extraordinary political force, in many ways right out of the American playbook. An outsider. Anti-Establishment. A builder. Bombastic. Confident. A fast-talking scrapper. But we also saw darkness. He could be petty. Cruel. Bored by American history and dismissive of governing traditions that had long guided elected leaders. Tantalized by the prospect of power. Eager to use fear to get his way. “Real power is—I don't even want to use the word—rear,” Trump told us. “I bring rage out. I do bring rage out. I always have. I don't know if that's an asset or a liability, but whatever it is, I do.” Could Trump work his will again? Were there any limits to what he has his supporters might do to put him back in power? Peril remains.
