The next date to list would be Valerie Plame's memo to her Section that Joe get the job. Or, it would be her staff meeting when the subject was discussed, whichever first occurred.
The magic State Department memo you list was dated the day before Wilson's article in the Times. But Times articles are usually available on the Net the night before. So, the State Department could have ginned up the memo that refers to "Valerie Plame" AFTER the Wilson article and in response to it, even though the facial date is after it.
I believe it has been established that Rove was not on the Africa trip. So whatever Powell was doing on that plane to make his Department seem less disloyal would not have reached Rove immediately.
Plus, your list would be more valuable if the money quotes that are now known from each transaction were put in after the date and communication. For example, 07/05 - State Department Memo on Wilson - refers to his wife as "Valerie Wilson"
Those are my suggestions.
Add in the Jan 13 Kerry campaign memo that shows Wilson as being part of the Kerry campaign.
Sorry my earlier post does reference a document from the Kerry campaign that refers to Jan 13 2003, but from things on it it seems like it is a typo, and should be 2004.
