One Officer Injured at Capitol Shooting Incident (UPDATED)

Very few details but lots of speculation

A woman driving a black Lexus tried to ram through a White House barricade Thursday, then led police on a chase that ended in gunfire outside the Capitol, witnesses and officials said.

Tourists watched the shooting unfold on Constitution Avenue outside the Capitol as lawmakers inside debated how to end a government shutdown. Police quickly locked down the entire complex for about an hour, and both houses of Congress went into recess.

The pursuit began when a car tried to ram a security barricade blocking the stretch of Pennsylvania Avenue in front of the White House, according to a law enforcement official who was not authorized to discuss the case by name and insisted on anonymity.

Witnesses said at least 20 police cars chased the Lexus toward Capitol Hill, where the car crashed outside the Capitol.
