NBC News is hunting the war criminal next door

NBC is hunting for the war criminals among us. The network is working on a series about international war criminals living in the United States, due to air this month or next. One of their first investigations involves a Maryland college professor who the network claims participated in the 1994 Rwandan genocide. A letter from the network to the university led to the school suspending the professor. Hot on the trail of the fallout of that investigation is Brian Stelter, media reporter for the New York Times, and he joins us now.
