Still seems fishy to me. I'd be surprised that even CBS would put their own marks on documents they wanted to broadcast, especially if they had already sent out unmarked copies to the WH or other outlets.
Are you sure USAT had all 6 memos on their pdf files from the beginning of this story? Again, their "text" file only provides text for the four memos used by CBS.
Hate to beat this to death, but it something doesn't smell right about these "new" memos.
They didn't mark up their "documents"; they marked copies of their "documents", as they have broadcast rules from their lawyers about showing an address, etc.
Their "documents" are copier copies purporting to be copies of the original memo, but are really copier copies of the fakes.
I have only someone else's word for it that when the White House got the faxes of the copies from CBS, they put them all on one file so the 2 worst of the forgeries were preserved with the 4 best that were broadcast.
