I’m trying to find more backstory, but for now here’s Politico’s report:

The latest video to surface shows a confrontation with a videographer at a rooftop event in Washington, D.C for Illinois Democratic Senate nominee Alexi Giannoulias. The clips appears to show guests confronting a video tracker and asked him to leave what they say is a private event, after which the camera moves downward and the videographer is heard saying incredulously, “you’re going to drag me out of this place?”

The NRSC’s memo alleges the videographer was “physically accosted by three men from the event.”

“Excuse me, this party is private, tonight,” said the man, a Giannoulias supporter, who confronted the videographer. “We paid for this part. Get off this part.”

“If you want someone to come and tell me that, that’s fine,” said the videographer.

“It is private, leave please,” said the Giannoulias supporter.

The memo also states that three men who “accosted” the videographer “appear to have been Giannoulias campaign staff members,” however a spokeswoman for the Democrat’s campaign said they were guests.

“While other individuals, including campaign staffers, are free to engage in polite conversation with a videographer, they are not free to be either verbally abusive to or make physical contact with a videographer,” Cairncross wrote in the memo. “Doing so potentially exposes both the individuals engaged in such contact and the campaign to liability for assault and battery.”

The videographer says his friend lives in the building and she invited him. The Democratic staffers (or financial backers) don’t care, and instead they get their Chicago thug on to drag him out of the area. But what else do you expect from the friends of Chicago mob banker Alexi Giannoulias?

This is, of course, the second video of Democratic assault in response to transparency attempts in the past week. Congressman Bob Etheridge (D-NC) decided to respond to questions by a high school student on a public street by physically assaulting the student.

Chicago thug tactics take Washington.
