 For a closer look now at the Republicans' shifting identity under Donald Trump and what it might mean for American democracy and the world, we are joined by Fiona Hill, a former top official on the National Security Council, and Robert Kagan is a senior fellow at the Brookings Institution and an editor-at-large for the Washington Post, the author of Rebellion, How Anti-Liberalism is Tearing America Apart Again. Good to have you both here.
