Dr. Leana Wen got her TV start as a CRISIS ACTOR during the 2013 Boston Bombing here with CNN Jake Tapper.

To me it looks like both Dr. Leana Wen & CNN Jake Tapper are still in the CNN STUDIO in front of a fake GREEN SCREEN BACKGROUND doing this fake interview. There are no shadows on their faces or sun on their cloths like the others in the background. Maybe a fan to occasionally blow Leanna's long hair.
These FAKE NEWS people are lazy and they do this a lot so I never put it past them.
