Over the weekend, a gunman killed 11 people at the Tree of Life Synagogue in Pittsburgh. It was the deadliest attack on Jews that the United States has ever seen. On this special episode, Katie and Brian talk with Jonathan Greenblatt, CEO of the Anti-Defamation League — an organization that fights against anti-Semitism and other racially-motivated hate. Jonathan talks about the rise of hate crimes in the U.S., the role of social media and political rhetoric, and what all Americans can do in the wake of this tragedy.
