From Greg Mitchell of The Nation: “Hundreds of protesters blocking intersections and ‘surrounding’ the convention center hosting a right-wing event with presidential candidates Herman Cain and Mitt Romney; major conservative party donors (and backers of the Tea Party) Charles Koch and David Koch said to be in the building. Brief video here.

Cops use batons on protesters and make multiple arrests. Car plowed through the crowd of protesters, ABC News and Washington post confirm at least two injured. Photo of injured protester on stretrcher. Livestream here.

UPDATE: Wash Post also reports two injured and also fights breaking out between protesters and others.

(Although I suspect that the “fights between protesters” may be a result of undercover cops sent to disrupt and discredit the protests, as happened with the disruptive faux protester whose conduct led to multiple arrests at Citibank).
