For more on what happened and why, let's bring in the U.S. ambassador to the United Nations, Dr. Susan Rice. Dr. Rice, thank you for joining us.
RICE: Good to be with you, Jake.
TAPPER: So, first of all, what is the latest you can tell us on who these attackers were at the embassy or at the consulate in Benghazi? We're hearing that the Libyans have arrested people. They're saying that some people involved were from outside the country, that there might have even been Al Qaida ties. What's the latest information?
RICE: Well, Jake, first of all, it's important to know that there's an FBI investigation that has begun and will take some time to be completed. That will tell us with certainty what transpired.
But our current best assessment, based on the information that we have at present, is that, in fact, what this began as, it was a spontaneous -- not a premeditated -- response to what had transpired in Cairo. In Cairo, as you know, a few hours earlier, there was a violent protest that was undertaken in reaction to this very offensive video that was disseminated.
We believe that folks in Benghazi, a small number of people came to the embassy to -- or to the consulate, rather, to replicate the sort of challenge that was posed in Cairo. And then as that unfolded, it seems to have been hijacked, let us say, by some individual clusters of extremists who came with heavier weapons, weapons that as you know in -- in the wake of the revolution in Libya are -- are quite common and accessible. And it then evolved from there.
