Your comment set off all kinds of bells and whistles in my head!
We've all suspected Hillary! is behind this memo. How about this scenario:
Hillary! devises the plan to use the Intelligence Committee for opposition research to use against the President and the Republicans. She convinces Rockefeller that the only way they can take the WH is to stir up enough dust about our reasons for going to war. A memo is produced outlining their stategy and distributed to the democrat members of the committee.
Hannity has said that we'd "be surprised" who leaked the memo to him. Suppose it came from Hillary!'s office as a means of getting rid of Rockefeller so she can become vice-chair of the committee? Would it be the first time a Clinton double crossed one of their own to gain more power?
