- The break-in at the White House makes the US Secret Service look terrible. It also sheds light on an agency that operates largely behind the scenes.
People in Washington have advice for those guarding the White House.
Lock the door, said a US congressman, Mike Rogers, on CBS's Face the Nation.
On Friday, a man later identified as Iraq War veteran Omar Gonzalez climbed a fence, ran more than 60m (197ft) and made it through the North Portico door.
One former Secret Service officer who asked not to be identified ("I'm a private person," he says) is as puzzled as anyone about his former colleagues - and "how hapless they seemed".
He says he's spent "many hours" standing at the North Portico door. He wonders how Gonzalez made it that far.
"I'm at a loss to explain why somebody didn't tackle him," he says.
Gonzalez was captured - once he got inside. He had a knife and 800 rounds of ammunition in a car parked blocks away, according to authorities.
