The US Secret Service has launched a security review to learn how an Iraq war veteran with a knife was able to get inside the White House after jumping a fence and sprinting 70 metres across the North Lawn - the first time that has ever happened.
Within seconds, the man - who was said to have been diagnosed with combat trauma - got to the doors of the North Portico and stepped inside. The man - Omar Gonzalez, 42 - was then subdued by an officer.
Agents found a knife in Gonzalez' trouser pocket, a Secret Service affidavit said.
