If you look up all of the videos, she says "It's Delores Huerto, my goodness..." then she says "Bernie is English only" over the people shouting "neutral..." This is the same video... only chopped up. If you watch the entire video, it shows this cam operator scanning the Hillary signs and supporters and they are all having a good time. She is upset with the Bernie supporters and that is why she says what she does... The woman who says it is a Hillary supporter.
