"Scrubbed" and the Smoking Gun

ABC News reports that the Benghazi talking points went through twelve versions in which the Obama Administration scrubbed the document of any reference to al Qaeda or terrorism or the warnings the Administration:

When it became clear last fall that the CIA’s now discredited Benghazi talking points were flawed, the White House said repeatedly the documents were put together almost entirely by the intelligence community, but White House documents reviewed by Congress suggest a different story. 

ABC News has obtained 12 different versions of the talking points that show they were extensively edited as they evolved from the drafts first written entirely by the CIA to the final version distributed to Congress and to U.S. Ambassador to the U.N. Susan Rice before she appeared on five talk shows the Sunday after that attack. 

White House emails reviewed by ABC News suggest the edits were made with extensive input from the State Department. The edits included requests from the State Department that references to the Al Qaeda-affiliated group Ansar al-Sharia be deleted as well references to CIA warnings about terrorist threats in Benghazi in the months preceding the attack.
 

The smoking gun in the story is an email from Victoria Nuland, Secretary of State Hillary Clinton's spokesperson:

State Department spokesman Victoria Nuland raised specific objections to this paragraph drafted by the CIA in its earlier versions of the talking points:

“The Agency has produced numerous pieces on the threat of extremists linked to al-Qa’ida in Benghazi and eastern Libya. These noted that, since April, there have been at least five other attacks against foreign interests in Benghazi by unidentified assailants, including the June attack against the British Ambassador’s convoy. We cannot rule out the individuals has previously surveilled the U.S. facilities, also contributing to the efficacy of the attacks.”

In an email to officials at the White House and the intelligence agencies, State Department spokesman Victoria Nuland took issue with including that information because it “could be abused by members [of Congress] to beat up the State Department for not paying attention to warnings, so why would we want to feed that either? Concerned …”

The paragraph was entirely deleted.
 

This is almost the definition of a cover-up... government officials deliberately obscuring facts that would make their own conduct look bad.
