Interesting. It looks like the Headline from Judicial Watch, who obtained the court ordered documents is correct, it says that the attack had been planned 10 days before the attack; not that the government knew of the attack 10 days prior to the event.
Legal Insurrection and the Gateway Pundit have identical, incorrect headlines. The rest of their articles seem to be lifted from Judicial Watch.
