Surprising this hasn't been posted before - Dem Memo on Politicizing Intelligence excerpt:

2) Assiduously prepare Democratic "additional views" to attach to any interim or final reports the committee may release. Committee rules provide this opportunity and we intend to take full advantage of it. In that regard, we have already compiled all the public statements on Iraq made by senior administration officials. We will identify the most exaggerated claims and contrast them with the intelligence estimates that have since been declassified. Our additional views will also, among other things, castigate the majority for seeking to limit the scope of the inquiry. The Democrats will then be in a strong position to reopen the question of establishing an independent commission (i.e. the Corzine amendment).

3) Prepare to launch an independent investigation when it becomes clear we have exhausted the opportunity to usefully collaborate with the majority. We can pull the trigger on an independent investigation at any time-- but we can only do so once. The best time to do so will probably be next year either:

A) After we have already released our additional views on an interim report -- thereby providing as many as three opportunities to make our case to the public: 1) additional views on the interim report; 2) announcement of our independent investigation; and 3) additional views on the final investigation; or

B) Once we identify solid leads the majority does not want to pursue. We could attract more coverage and have greater credibility in that context than one in which we simply launch an independent investigation based on principled but vague notions regarding the "use" of intelligence.

There have been some harsh responses to this leaked memo, such as this one by Senator Kyl:

Republican Senator Jon Kyl of Arizona on that Democrat memo: "This strategy memo lays bare what we've started to see for some time: an orchestrated effort by Democrats at a time of war to improperly use an intelligence investigation as a weapon against President Bush. The memo completely shreds Democrats' claims of bipartisanship in this investigation and falsely attributes ugly motives to the President, members of his administration, and fellow members of Congress. It has reached conclusions about this investigation before it's even been concluded. The Senate should examine whether its rules have been violated by this memo. It is, for example, improper under Senate rules to impugn the motives of fellow Senators. Additionally, committee staff should never be involved in partisan political scheming, most especially Intelligence Committee staff members, who in the past have always acted in a nonpolitical, bipartisan fashion. If Senators continue to attribute this memo to staff, then those staff members should be fired. Additionally, I call on Senator Rockefeller and Senate Democratic leaders to immediately disassociate themselves from this partisan attack plan. A failure to denounce this memo publicly would clearly seem to be an acknowledgement of its authenticity."

Perhaps the harshest response comes from Senator Zell Miller, D-GA:

“Of all the committees, this is the one single committee that should unquestionably be above partisan politics. The information it deals with should never, never be distorted, compromised or politicized in any shape, form or fashion. For it involves the lives of our soldiers and our citizens. Its actions should always be above reproach; its words never politicized.

“If what has happened here is not treason, it is its first cousin. The ones responsible - be they staff or elected or both should be dealt with quickly and severely sending a lesson to all that this kind of action will not be tolerated, ignored or excused.

“Heads should roll!”
