(CNN) -- A witness who was on the base of the U.S. Capitol steps said he saw a black sedan, chased by police cruisers, stop at a grove of trees. Police drew guns and tried to get the driver out. The vehicle went into reverse and officers opened fire, Frank Schwing told CNN. "It was pretty chaotic all over," he said of the Thursday afternoon incident.
