Obviously, there are political operatives that are playing a role. It doesn't mean it shouldn't be denounced. All candidates should say, we want to have - be able to have nonviolent, peaceful speaking events. Do not hurt people, do not hit. Do not break the law, no one is encouraging violence. That's what should be stated very clearly. Denounce any violence that occurs. Be honest to say exactly also, what is behind this. They are trying to elicit and produce a specific response to try to discredit and to paint Donald Trump in a particular light. That is - that's what's happening.
