That may be bit the video does not prove this at all. This simply adds noise. I need to see emails where Chris Hayes shares his questions and somehow provides input on her answers. That he is friendly towards Hillary and gives her the questions ahead of time for an “on air” interview simply does not cut it.
Much like the talk show hosts and their Hollywood guests prepare to show a 'clip' of their latest movie while the 'guest' pretends they knew nothing about it and feign surprise.
