Secretary of State Hillary Clinton is vowing a full investigation of the alleged security lapses that led to the killing of four Americans at the U.S. consulate in Benghazi, Libya, last month. House Republicans have set a hearing for next week following claims the State Department rebuffed pleas from U.S. officials in Libya for more security before the attack. On Wednesday, Clinton vowed a thorough probe.

Secretary of State Hillary Clinton: “The men and women who serve this country as diplomats deserve no less than a full and accurate accounting, wherever that leads. And I am committed to seeking that for them and for those who made the ultimate sacrifice in service to our nation. No one wants to determine what happened that night in Benghazi more than the president and I do. No one is more committed to ensuring it doesn’t happen again. And nobody will hold this department more accountable than we hold ourselves.”
