Dr. Jeffrey Kaye "Iron Man” & the OBL Cover Up.
From Corbett Report Radio: In the run-up to 9/11, a little-known military intelligence unit was tracking the movements and actions of Al Qaeda and Osama Bin Laden. In late 2000, the military brass called off that work, and later the DoD lied to Congress about the unit and its work. As James says, get your pen and paper in hand, you might want to take notes on this one.
Kaye get's into military intelligence other then Able Danger prior to 9/11.
