The United States Capitol was placed on lockdown Thursday afternoon after a woman tried to ram her car into the White House gate, was chased by Secret Service and killed in an exchange of gunfire with Capitol police, sources said.
It started at 2:18 p.m. when the woman in a black Lexus 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.
Her car hit a Capitol Police vehicle at Second St. and Constitution Ave. and then crashed into barricades a few blocks away, Dine said.
Law-enforcement sources said she began firing and was shot. The child was reported to be safe.
"This appears to be an isolated incident," said Capitol Police Chief Kim Dine. "Both scenes are under control."
Her motive was unknown but Dine said there was no reason to think it was an act of terrorism.
Rep. Gerry Connolly, who was on the balcony talking to his colleagues, described a "burst" of gunfire from the House side of the Capitol, towards the House office buildings.
"It was like the first volley in a 21-gun salute," Rep. Matthew Cartwright told MNSNBC.
Rep. Tulsi Gabbard, D-Hawaii, describes the scene near her Cannon House office. Gunshots were reported on Capitol Hill on Thursday, October 3.
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.
