People leave work early so they can get home to watch The Beat with Ari Melber. He explains politics, the law-and hip-hop-like nobody else on TV. At our March episode Ari explored the world of cable news and how he manages to keep it all straight when events are cascading around us minute by minute. And that includes the names of all the Russian oligarchs. Ari was joined by author of "Zucked" Roger McNamee - discussing his superb (NY Times) book about the dangers of Facebook. Peter Riegert read Chapter VII of our serialized novella "Author to Come," written by author Shalom Auslander (Foreskin's Lament, Hope: a Tragedy). Curator of Painting and Sculpture at MoMA Ann Temkin explained the museum's current shopping spree. And there was a special appearance by Mo Rocca and CBS Sunday Morning correspondent Martha Teichner. Jazz Legend Jay Leonhart leads the 1-Train Band.
