The C.I.A. analysts quickly scrubbed references to Al Qaeda from the key part of the draft, investigators on Capitol Hill now tell me.

On Friday evening of Sept. 14, the updated talking points were e-mailed to the relevant officials in various departments, including Nuland. She wondered why the C.I.A. was giving members of Congress talking points that were far more assertive than anything she could say or defend herself. She also noted that the talking points left the impression that the C.I.A. had issued all sorts of warnings before the attack.

Remember, this was at a moment when the State Department was taking heat for what was mostly a C.I.A. operation, while doing verbal gymnastics to hide the C.I.A.’s role. Intentionally or not, the C.I.A. seemed to be repaying the favor by trying to shift blame to the State Department for ignoring intelligence.

Nuland didn’t seek to rewrite the talking points. In fact, if you look at the drafts that were written while she was sending e-mails, the drafts don’t change much from one to the next. She was just kicking the process up to the policy-maker level.

At this point, Nuland’s participation in the whole affair ends.

On Saturday morning, what’s called a deputies committee meeting was held at the White House. I’m told the talking points barely came up at that meeting. Instead, the C.I.A. representative said he would take proactive measures to streamline them. That day, the agency reduced the talking points to the bare nub Susan Rice, the American ambassador to the United Nations, was given before going on the Sunday talk shows.

Several things were apparently happening. Each of the different players had their hands on a different piece of the elephant. If there was any piece of the talking points that everybody couldn’t agree upon, it got cut. Second, the administration proceeded with extreme caution about drawing conclusions, possibly overlearning the lessons from the Bush years. Third, as the memos moved up the C.I.A. management chain, the higher officials made them more tepid (this is apparently typical). Finally, in the absence of a clear narrative, the talking points gravitated toward the least politically problematic story, blaming the anti-Muslim video and the Cairo demonstrations.

Is this a tale of hard intelligence being distorted for political advantage? Maybe. Did Victoria Nuland scrub the talking points to serve Clinton or President Obama? That charge is completely unsupported by the evidence. She was caught in a brutal interagency turf war, and she defended her department. The accusations against her are bogus.
