Hmm well the video is blocked in my country and I'm too lazy to view it on Tor, but hand signals are something that many politicians have done before and admit to. It's certainly plausible for a politician to set up hand signals with a television crew to signal when to change topics or end a topic to make them look good. A lot of networks are biased towards one candidate over another, so to me this is kind of a given. Not really shocked or surprised by it to be honest.
