Bob's Blog: New York City on edge as tensions boil over

Tensions remain high in New York City, as the community lays to rest the first of two police officers murdered last week in the line of duty. People are defying Mayor Bill de Blasio's public requests for a moratorium on demonstrations - they've returned to the streets to protest what they call unfair police tactics. We'll be joined by NYPD Commissioner Bill Bratton and former NYC Mayor Rudy Giuliani to discuss this issue that has been a challenge all year and has reached a fever pitch in America's biggest city.

We will also sit down with Ebola czar Ron Klain, who has coordinated the Obama administration's response to the deadly virus since October. The situation in the U.S. has been contained but the disease rages on in West Africa and recent mistakes at the CDC show that simple errors can hurt the containment efforts. What more can be done?

There is also some foreign policy news to discuss - including the standoff with North Korea over the Sony Pictures hack, and the drawdown of American troops from Afghanistan. To help us break it all down, we'll talk to David Rohde of Reuters and Robin Wright of the U.S. Institute of Peace.

Finally, we'll talk to author Laura Hillenbrand, whose epic biography of war hero Louis Zamperini is portrayed in the film "Unbroken." The movie, directed by Angelina Jolie, was released on Christmas Day. Click here for a preview of our interview, which will air in full on Sunday.

We hope you'll tune in. Check your local listings here.

Happy holidays to all!
