Washington — U.S. intelligence and counterterrorism officials are testifying before Congress about the deadly September attack on the U.S. consulate in Benghazi, Libya.

The House and Senate Intelligence Committees began closed-door hearings Thursday on the attack. Former CIA director David Petraeus is among those scheduled to appear before the House committee Friday.

Sen. John McCain was joined by Sens. Lindsey Graham, R-S.C., and Kelly Ayotte, R-N.H., in calling for a temporary Senate committee established specifically to investigate Libya.

The call for what would effectively be a new investigation comes as lawmakers continue to pry into the administration's narrative on what happened before, during and after the attack that killed four Americans.
