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.

Trump runs into trouble with his ban, his budget, and his health care bill. Then, Barack Obama’s former Deputy Chief of Staff and Health Care Czar Nancy-Ann DeParle joins Jon and Dan to talk about the fight to pass and now save the Affordable Care Act.
