The guy to the left of DeBlasio is non other than a local Long Island City, NY politician Jimmy Van Bramer. He's the idiot who shut down He Will Not Divide Us for an afternoon and held a rally with his own supporter, used the cops to throw opposition out, problem is the Museum HWNDU was hosted on is a non-profit, he broke the rules, but he always breaks the rules, crony local cheap politician he is.

BTW - HWNDU is back and its in Poland, hewillnotdivide.us and no one cares, basically a ghost town.
