I'm glad you cleared that up. I think No-facts went to some pains to try to clarify it was NOT a WH person but an "administation" source, which I interpreted to mean State Dept, i.e. Richard Armitage or Colin Powell (for whom everyone likes to provide cover).
When Fitzgerald arrived, he had a third waiver in hand -- from Bill Harlow, the CIA public information officer who was my CIA source for the column confirming Mrs. Wilson's identity. I answered questions using the names of Rove, Harlow and my primary source.
We know,
1. Rove was 1 "Senior Administration Official"
2. Bill Harlow was the CIA source.
3. Fitz KNEW the identity of the other Senior Administration Official BEFORE he talked to Novak.
Since Harlow was the CIA source, the CIA Director (Name? Mental Blank) can be discounted as the other Sr. Admin Official.
The Primary Source had to be someone like Rove and who had access to info such as this. My guess is Andrew Card or someone very close to him.......
