(CNN) -- Secretary of State Hillary Clinton will testify on the deadly attack on the U.S. consulate in Benghazi, Libya before the House of Representatives Foreign Affairs Committee on December 20, the committee announced Wednesday.
The September 11, 2012 attack resulted in the deaths of four Americans including Ambassador Chris Stevens and called into question the security of U.S. diplomatic personnel abroad.
While Clinton did go to the Hill to brief congressional members behind closed doors soon after the attack, she has not been back since. Next week's testimony is expected to be proceeded by the release of the findings of an independent review of the State Department's handling of security and the threats in Libya. The review, requested by the Accountability Review Board, is headed by former U.S. ambassador Thomas Pickering and includes former Chairman of the Joint Chiefs of Staff Adm. Mike Mullen.
Another issue that is bound to be focused on is how the administration spoke of the attack in the days following September 11th. U.S. Ambassador to the U.N. Susan Rice, whose name has been floated as a replacement for Clinton after she leaves her post as secretary of state, said preliminary information suggested the attack was spawned from protests over an anti-Muslim film. Rice's comments came under harsh scrutiny as further information suggested the attack was a premeditated assault.
Clinton has defended Rice in the wake of criticism.
Former CIA Director David Patraeus testified behind closed doors before the Senate Intelligence Committee about the attack in November.
Clinton will also testify before the Senate Foreign Affairs committee though a date has not been announced yet.
