The Republican notion that it was obvious from day one that the attack was preplanned and unrelated to what had occurred in Cairo (which certainly WAS about the video) is massively overstated.
Both Al-Jazeera and Al-Arabiya reported that there were protests over the video in Benghazi.
It’s worth reading what Newt Gingrich had to say about the attacks at the time:
CNN Anchor John Berman asks if Gingrich has proof of there being a connection between demonstrations and attacks in Egypt and Libya. Gingrich replies, “…. Anybody who’s ever studied terrorism will tell you, there’s almost certainly a link. This is a lot like the Danish cartoon outrage a few years ago…. We are faced with enemies who want to defeat the United States and impose their radical views…. How can the US government apologize for a film no one has seen, which is what the Embassy in Cairo did yesterday…. It’s not just about an event in Libya. It’s about a longer war, part of which we were being reminded of yesterday on 9/11.”
And Marco Rubio described the events in Cairo and Benghazi as senseless mob violence (see p 78 of the recent email dump - Rubio’s original statement has apparently been scrubbed from the internet).
