The guys with the camera are jerks, too.
Yours is a supposition. As they first posted this on Breitbart it's more than likely accurate. However, you cannot tell that from the video. They asked a question on camera and then were assaulted by the congressman, who has sense apologized, btw.
Asking a question "Do you support the Obama Agenda?" on camera is not an unequivocal sign of jerkdom. Being affilitated with Breitbart may very well be.
