"No law enforcement personnel were injured during the incident," the Secret Service said. And no shots were fired, they said.
A later statement from the Secret Service did not identify the woman, but it said she was 35 years old from La Vergne, Tennessee. The agency said that she drove into the security barrier outside the White House intentionally, but the van never breached the perimeter.
"The Secret Service has had previous encounters with the female in the vicinity of the White House resulting in numerous arrests for a variety of criminal violations," the statement said. "The female was again charged today with numerous criminal violations and transported to the Metropolitan Police Department. The White House complex has returned to normal operations.”
Police said they saw a gun in the woman’s hands which was pointed in the opposite direction of officers during the incident, and she allegedly refused to drop the gun and had it taken from her, according to police documents.
The woman allegedly said she had a "BB gun" because if "James Burris" was president officers would shoot her to protect him, according to the documents. She was charged with carrying a pistol without a license, possession of an unregistered firearm or destructive device, assault on a police officer, destroying government property and other charges, according to the police documents.
