There was absolutely no intention of allowing any substantive testimony. Hillary is out of the country, and Petraeus is refusing, and of course his majesty will never be subpeoned. If either were to testify, they would most likely have an unfortunate fatal accident.
If Petreus feels his life is in danger, he should hand write everything he knows and send it to people that are investigating in case something happens to him-like a “suicide” you know because he’s so distraught. Someone has GOT to out BO for what he has done.
