As Josh wrote last night, Vice President Cheney’s office has had some bad luck with safeguarding classified material.

And no wonder. According to Rep. Henry Waxman (D-CA), White House officials have a bad habit of leaving classified documents unattended and then shutting down security officers when they seek to investigate. Things are so bad, officers from the White House Security Office have told Waxman, that over half of the staff from that office has resigned in the past year.
