Emails sought by congressional Republicans showed that Nuland expressed concern that any mention of prior warnings or the involvement of al-Qaida in the talking points would give congressional Republicans ammunition to attack the administration in the weeks before the presidential election.
She had sought removal of a reference to a CIA warning about the potential for anti-American demonstrations in Cairo and jihadists trying to break into that embassy.
Testifying at her confirmation hearing in July, Nuland said she objected to some of the administration's talking points in the days after Benghazi because they were inconsistent, inaccurate and risked prejudicing the FBI investigation into those responsible for the attack.
"It was not for me to decide what we knew or what we could declassify," Nuland told the Senate Foreign Relations Committee.
Nuland is a career foreign service officer who has held senior positions in the George W. Bush and Obama administrations. She also has served as a foreign policy adviser to former Republican Vice President Dick Cheney.
