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 Department of Justice indicts 13 Russian nationals who conducted information warfare against the United States, Mueller’s charges offer hints about his next move, Trump reacts on Twitter with his characteristic subtlety and cool, and the students of Stoneham Douglas lead a movement to stop mass shootings. Then Lovett talks to New York Times writer Zeynep Tufekci about Facebook’s role in the Russia indictments and whether mass shootings are contagious.
