One of the most secretive military campaigns in U.S. history is under the microscope like never before. In a major exposé based on leaked government documents, The Intercept has published the most in-depth look at the U.S. drone assassination program to date. "The Drone Papers" exposes the inner workings of the U.S. military’s assassination program in Afghanistan, Yemen and Somalia, revealing a number of flaws and far more casualties than the intended targets. The documents were leaked to The Intercept by an unnamed U.S. intelligence source who says he wanted to alert Americans to wrongdoing. We are joined by The Intercept’s Jeremy Scahill, lead author of the exposé, "The Drone Papers."
