This week Katie and Joe take a look at what's happening on Capitol Hill with Julie Hirschfeld Davis the new congressional editor for the The New York Times. Julie has covered politics from Washington for two decades, writing on Congress, three presidential campaigns and three presidents. She is a CNN political analyst and next month Julie and Mike Shear have a new book out, Border Wars: Inside Trump’s Assault On Immigration, the inside story of how Trump and his team seized on immigration as a defining political issue and have redefined how America thinks about immigration and immigrants.
