From the April 15 edition of CNN's CNN Tonight with Don Lemon:
DON LEMON (HOST): Speaking of Cleveland, Donald Trump has insinuated that there may be riots at the convention if he gets the most delegates and isn't nominated. His former campaign adviser Roger Stone said this in a web interview earlier this month.
[…]
LEMON: So Mr. House, he mentions Pennsylvania, but it's clear he is talking about any delegate. Are delegates going to be intimidated by that?
STEVE HOUSE: I hope not. We've been talking to them about it. He actually came out here and did a radio interview and he talked about the Colorado delegation in the same vain. We've talked to our folks about, first of all, there's going to be a lot of pressure in this. I mean, this is a very, very important time with a big decision. So, if you can't handle pressure, you need to come to us and we can help you navigate your way through it. But there's no question that delegates, unpledged or pledged, if this convention is contested, will have to face pressure.
LEMON: Do you think he's inciting violence?
HOUSE: I hope not. I hope that people understand that what he's suggesting is that there's going to be a lot of contact and you need to prepare yourself. I think his statement, I wouldn't have made the statement, but I do think that our delegates ask about it even last Saturday and they continue to do that in e-mail. And I think they’re getting prepared for it. I think he probably gave us a heads up on what’s going to happen.
