Four former aides to President Obama — Jon Favreau, Dan Pfeiffer, Jon Lovett, and Tommy Vietor — are joined by journalists, politicians, comedians, and activists for a freewheeling conversation about politics, the press and the challenges posed by the Trump presidency.

The human toll of Trump’s shutdown grows as he plans a primetime address, Democrats debate how to talk about impeachment, and Alexandria Ocasio-Cortez triggers conservatives by doing literally anything. Then the Washington Post’s Dave Weigel talks to Tommy about his coverage of Elizabeth Warren’s first trip to Iowa as a presidential candidate.
