U.S. special forces gather intel in Libya; Sensitive documents found on compound floor

CNN's Barbara Starr has learned U.S. special forces are now in Libya and neighboring countries helping to gather intelligence on the suspected Libyan militia responsible for killing ambassador Chris Stevens and three other Americans.

This comes as the FBI began searching the consulate in Benghzai, Libya today - more than three weeks after the September 11 attack.

OutFront tonight: Washington Post correspondent Michael Birnbaum. He visited the consulate a day before the FBI arrived this week and found sensitive documents lying around the site.

FBI visits site of attack in Libya

Three weeks after four Americans were killed in an attack on the U.S. Consulate in eastern Libya, an FBI investigative team arrived at the site, a U.S. official said Thursday.

"You should not assume that all we could do or have been doing is restricted solely to Benghazi," Attorney General Eric Holder told reporters in Washington. "There are a variety of other places in country and outside the country where relevant things could be done and have been done. This is a matter that's been under active investigation almost since the time of the incident and I'm satisfied with the progress that we have made."

He said the focus of the Justice Department was "to solve this matter, to hold people accountable. So that's what we will do."

A senior administration official told CNN the team arrived late Wednesday and worked through Thursday.
