TAPPER: Have you looked into whether or not Democratic operatives paid by the Democratic National Committee were actually instigating these horrific actions, these violent actions we saw at Trump rallies? That's -- I'm sure you would agree, if that's true, that's really offensive.That doesn't get the DNC off the hook. Why were these people hired? They did something, and then they were hired. Were they hired because they'd shown what kind of dirty tricks they were capable of?
MOOK: Well, violence is unacceptable. These individuals no longer have a relationship with the DNC. They have never had a relationship with the Clinton campaign. And my understanding is that the events that are referenced happened, I think, in February of last year. They didn't have a contract with the DNC until June.
MOOK: But, putting that all aside, this was, again, a video that was leaked out for the purpose of damaging the campaign. It's edited, so we don't know what the full context is. And there is -- there's no evidence whatsoever that we have been able to find that anyone ever did anything like this when they were working for the DNC.Mook sounds so guilty there. He's mad that any video exists (because it hurts his candidate), and he's also telling us not to make any inferences about anything that isn't proved by video. Again, I'm thinking: They did something bad before they were agents of the DNC, so why did the DNC hire them and what did they do?
