The debate over the Benghazi terror attack flared once again Thursday as senators grilled a diplomatic nominee over her role in massaging the Obama administration’s initial story-line on the attack.

Republican senators repeatedly challenged Victoria Nuland, nominated as chief U.S. envoy for Europe, during her confirmation hearing before a Senate panel. The post typically would not receive this much scrutiny, but Nuland’s prior job was as the top spokesperson in the State Department — she was the face of the department in the days and weeks following the Benghazi attack.

Republicans say the full truth has not yet been told, and prodded for answers on the role Nuland played in pushing to change the so-called “talking points” after the attack. Those notes were ultimately used by then-U.N. Ambassador Susan Rice to give a faulty account to the public about the nature of the attack.
