disgusting what he was doing. this was not handles the way bernie sanders handlings his problem. i have a lot of fans and they were not happy about it. this was a very obnoxious guy, a troublemaker looking to make trouble. i didn't get to see the event. >> reporter: so, it's interesting to hear him defending the supporters who roughed up this guy. this protesters said he was punched inned face, kicked in the neck, kicked in the chest, kicked in the stomach. he said someone stepped on his hands and some of these supporters called he and his fellow protesters the "n" word and also monkeys. trump warned last summer, after black lives matter protesters disrupted a bernie sanders event, he said that will never happen with me. we're going to have a fight on our hands if that happens. i don't know if i'll be doing the fighting myself or if other people will. so, in some ways, it seems like he sort of predicted this would happen, carol. >> so, where was the security?
