I had not heard that...all that I know for sure is that the documents are supposedly related to a memo that came from Justice saying that the Attorney General and the President were not involved and HAD NO KNOWLEDGE of this escapase or cover up of.

Then, suddenly Holder said that memo has to be retracted...the committee than asked why and can we see how you arrived at that conclusion, and THOSE are the documents that Holder will not give up.

THAT is my understanding, but in something like this...who knows.
