The Presidency of Donald Trump has been unlike any other in America’s history. While many of his core promises remain unfulfilled, he managed to reshape our politics in just four years. On the cusp of the 2020 election, David Remnick assesses the Trump Administration’s impact on immigration policy, the climate, white identity politics, and the judiciary. He’s joined by Jeannie Suk Gersen, Jonathan Blitzer, Bill McKibben, Keeanga-Yamahtta Taylor, and Andrew Marantz.
