Someone said this to me on facebook when I asked them what, exactly, they thought was being covered up in Benghazi. Apparently, the link to Al Qaeda was completely unknown until last month.

Except Hillary Clinton said this on September 26:

What is happening inside Mali is augmented by the rising threat from violent extremism across the region. For some time, al Qaeda in the Islamic Maghreb and other groups have launched attacks and kidnappings from northern Mali into neighboring countries. Now, with a larger safe haven and increased freedom to maneuver, terrorists are seeking to extend their reach and their networks in multiple directions. And they are working with other violent extremists to undermine the democratic transitions under way in North Africa, as we tragically saw in Benghazi.
