Mayor Jean Quan, in DC for the U. S. Conference of Mayors’ winter meeting, ran afoul of Occupy DC protestors who recognized her and surrounded her cab outside the Capital Hilton Thursday. As the video shows, it didn’t take the cops long to clear a path. Quan took it in stride, telling the Oakland Tribune’s Matthew Artz this morning: “We were busy talking away, and I looked up and there were all these protesters there. I think they freaked out the taxi driver.”
