Who's Responsible for State Dinner Security Breach?

While the Secret Service has taken responsibility for the high-profile White House security breach, Washington insiders are beginning to suggest that the White House Social Office is partially responsible for allowing gatecrashers at President Obama's state dinner last week.

On "Washington Unplugged" today, Amy Argetsinger of the Washington Post told CBS News correspondent John Dickerson that there should have been a member of White House Social Office assisting the Secret Service at the initial security checkpoint.

The Social Office staff "are the people who are familiar with who is supposed to be on the guest list and who isn't; the names, the faces the backgrounds of people," she said. "And if there is some kind of glitch with a VIP, perhaps it shouldn't be a young guard at the front who is having to deal with an irate VIP who doesn't understand why they are not being let in right away. That is something that should be up to the Social Office to smooth over, and act sort of like an auxiliary gate-keeper."

Argetsinger was one of the first people to report the attendance of the party crashers at the dinner. Her Washington Post colleague saw the Salahis walk in on the red carpet and recognized them as "horse-country" socialites who were not on the White House guest list.

Argetsinger then noticed that Michaele Salahi had announced on her Facebook page that she was at the State Dinner. "While we did break the story," said Argetsinger, "the Salahis sort of broke it themselves, in a weird way."
