White House staff and reporters have been allowed to re-enter the building following an evacuation on Friday night by the secret servicewhich was sparked when an intruder was spotted running on the grounds of the complex shortly after President Barack Obama had left the building.
Obama had just left aboard the Marine One helicopter for Camp David, the presidential retreat in nearby Maryland, when armed, uniformed secret service personnel ordered the press corps and members of the White House staff to evacuate. They were allowed back in after about half an hour, a witness said.
A secret service officer said the alert was sparked by an intruder who jumped over the White House fence.
There were no further details immediately available.
