WASHINGTON (AP) — The deputy CIA director has told lawmakers that UN ambassador Susan Rice was provided with an unclassified version of what happened during the deadly Sept. 11 attack in Libya that later proved to be incorrect.

CIA deputy director Mike Morell briefed members of the House Intelligence committee on Thursday. Emerging from the session, Democratic Rep. Adam Schiff said Morell told the panel that Rice was given an initial assessment that a spontaneous protest over an anti-Muslim video evolved into an attack on the consulate.

Rice’s comments on national talk shows five days after the attack has drawn fierce criticism, with some Senate Republicans vowing to block her nomination if she is tapped to replace Secretary of State Hillary Rodham Clinton.

Schiff said the ambassador’s interview remarks were based on the ‘‘best initial assessment.’’

Republican Congresswoman Ileana Ros-Lehtinen of Florida, who heads the House foreign affairs committee, said Clinton will testify after the State Department’s internal review of the attack is complete. Ros-Lehtinen says she expects the report’s completion in December.

The State Department declined to confirm Ros-Lehtinen’s announcement Thursday.

Department officials have said their review may not be finished until January, meaning that any appearance by Clinton before Congress could possibly be delayed.
