Nothing to support your statement. The lady was NOT knocked out, she stumbled and fell backward. The incident was outside the venue , Trump did not joke about it because he didn't know about the incident at the time. I have read something like 5 different reports and not one says anything about anyone seeing the lady get hit. Some have said she touched the man, some say that he touched, not hit, her. It was also pointed out in 2 of the reports that the man is 73 years old. The woman is 69 and a proud protestor since the Vietnam days. Still no word or recognition that the protestors are spitting on Trump supporters, hitting them with food, physically hitting supporters, screaming and pushing Trump supporters. And when they have caused a reaction, scream about being assaulted.
