According to Breitbart:
The establishment media was forced to cover O’Keefe’s videos after one subject, Robert Creamer, announced he would quit working for the DNC. This break came a day after the first video release prompted another subject, Scott Foval, to leave his job with another Democratic political group, Americans United for Change…
…Scott Foval of AUFC on 09/15/16 “So, I’ll give an example. In Iowa. Progress Iowa has a built-in group of people that they can message, who will show up. But what they will not do, is do that unless someone is paying them on the proiect. Because there’s staff time involved, there’s transportation involved, there’s food, lodging, training, whatever, involved….
….SCOTT FOVAL : We have to be really careful. Um, because, what we don’t need is for it to show up on CNN that the DNC paid for ‘X’ people to … that’s not gonna happen. We need to keep it, you know, I hate to use the Beyonce term, “partition,” but we need to keep the partition.
O’Keefe also highlights the DNC hiring people to aggressively bird dog Trump rallies. ” ‘Bird dog’ is a term used by the group to describe face-to-face pressure on GOP supporters. Foval emphasizes that the goal of ‘bird-dogging’ is to create a sense of ‘anarchy’ around Trump.”
