Sources on the scene indicate that there is a heavy police presence in the area, though it is unclear if it is much greater than the already massive police presence the Capitol building harbors. Some reports suggest that at least one police officer at the Capitol has been injured, but the nature of the injury and its extent are unclear.
The shooting comes after three days of a government shutdown. The shut down, which resulted from a break down in negotiations over a Federal Budget, has angered many Americans.
