State Department spokesperson Victoria Nuland starts an email chain about an imminent New York Times article written by Eric Schmitt that could mention a particular CIA annex. The email is sent to a handful of Clinton’s top aides.
Soon, a secret CIA official joins in the email chain, despite not being sent the original email.
A later email in the chain from this CIA official (or possibly another one) reveals the New York Times backs down and agrees to changes to the article, including not mentioning details about the CIA annex.
Parts of Clinton’s email will later be deemed classified due to the mention of at least one secret CIA official’s name and email address earlier in the chain. (US Department of State, 12/31/2015)
That evening, The New York Times publishes an article written by Eric Schmitt and two others called, “Deadly Attack in Libya Was Major Blow to CIA Efforts.” (The New York Times, 9/23/2012)
