Obama was probably on vacation and missed the hundreds of emails warning him that Iraq militants began their buildup the very day he announced a complete troop withdrawal against all experts advice. He probably had a beer with the terrorist leader the day he released him from prison.
Maybe they had a computer crash, and lost all those e mails. Well, if the IRS can use that excuse, why not the White Hut? Anyway, that is their story, and they are sticking with it. Oh yes, I forgot to mention. It's Bush's fault, and they sticking with that one too.
