Immediately after the debate, a huge stampede of reporters were charging towards the candidates. Reporter Andrea Mitchell, near the front of the crowd, fell down and the crowd didn't appear to slow down. There was a real risk that she was going to be trampled.

Bernie Sanders charged forwards, shouting for the reporters to make way, and was able to stop the onrush of reporters. Then, he helped Andrea Mitchell to her feet. "Are you all right?" he asked her.

She said she was. "That was a dangerous situation," she added.
