U.S. Deputy Secretary of State William Burns flew to Libya Thursday for meetings about the attack that killed U.S. Ambassador Chris Stevens. Secretary of State Hillary Clinton gave closed-door briefings to Congress about last week's attack. But there is likely to be little public information from these classified briefings.

Securing America.

The nation's top counter-terrorism official, Matthew Olsen, publicly acknowledged that individuals in Libya could be connected to al-Qaeda in the Islamic Maghreb.

(Olsen) "Yes, they were killed in the course of a terrorist attack on our Embassy."

Identifying a leading suspect or mastermind behind the attack is still premature, according to a U.S. intelligence official, speaking to FOX News.  The FBI, as of Thursday morning, had still not made it to the crime scene.

Questions as to why the militants were able to breach the U.S. consulate in Benghazi remain unanswered, as do the details of Stevens' security team.  Secretary of State Clinton must now provide a bipartisan panel and report back to Congress in 60 days, but that deadline reaches beyond Election Day, in mid-November.
