The suspect — who sources said had a child in the car — was shot and killed, and a shelter-in-place order was lifted at about 3 p.m. At least one Capitol Police officer was injured but apparently not shot.
"This appears to be an isolated incident," said Capitol Police Chief Kim Dine. "Both scenes are under control."
President Barack Obama was briefed about the harrowing incident, which came in the midst of the government shutdown that has created a tense atmosphere on Capitol Hill.
It started a little after 2 p.m. when the woman in a black car tried to breach White House security at 15th St. and E, law-enforcement sources said.
She did not get through and was chased at high speeds for about 12 blocks, the sources said. Near the Capitol building, she began firing and was shot, the sources said. The child was reported to be safe.
Her motive was unknown but Capitol Police said there was no reason to think it was an act of terrorism.
Travis Gillbert, who watched the chase from the roof of the Newseum, said vehicles involved "had several close encounters with other vehicles during the case."
"It was very dangerous," he said.
An NBC satellite truck operator saw several police cars with lights flashing near the gardens below the Capitol when he suddenly heard rapid-fire shots. Several police cars could then be seen chasing the black car, he reported.
The FBI responded to the scene, and a helicopter landed in front of the Capitol to medevac the injured officer.
A message from the Capitol Police ordered anyone in a House office to "shelter in place," but that order was lifted a short time later.
The House recessed, and the Senate went into a quorum call — dispensing momentarily with its official business — shortly thereafter.
