It is my take that like these tapes, Issa and Grassley have much more that they know and they are going to string this out until heads do roll.
Good take. That is my hope. This issue cannot be allowed to simply slide off the radar. Those involved are scared shiiteless over this. They got caught big time. Exactly who all of those involved are remains to be seen. Perhaps that is part of the Issa/Grassley play. To effectively flush the game before loosing the hounds.
