Is that right? USA Today has had six memos in pdf all along? I'm really curious why their "text" reference in the original article only includes the text of the 4 memos. Why did they leave out the text of the other 2? Wierd.
CBS had 6 right along. CBS sent all 6 to the WH, and the WH forwarded them to all the media.
The text of 4 is relevant, because those 4 are the ones that CBS asserts are genuine in a broadcast, and subsequent affirmation of authenticity. CBS chose, for whatever reason, to not use the other 2. Sort of like having reams of documents, and finding one that tells the story. No big deal, unless one is digging for inconsistencies in the bigger picture.
