Was this scheduled before or after the Able Danger information came out?
If before, I wouldn't count on this meeting to be what it is advertising, in fact, it might not happen.
If after, then it will be a CYA session, telling everyone that it wasn't their fault that they discounted boxes of documents that they SHOULD have included in their report.
These are controlled meetings with controlled agendas. I doubt that Able Danger will be allowed to rear its' head at the meeting.
However....outside the meeting hall might be a different story.....Unless Jamie builds a wall so that THE PEOPLE OF THE UNITED STATES cannot speak.
