My calculated guess is that ALL orders come from headquarters.
"Headquarters" being either Valerie Jarrett or David Axelrod.
Often people like Obama and Hillary are simply actors following the script and reading the lines that are fed to them by headquarters. In the case of Hillary's statement it may have been an ad-lib she threw in after being told to BLAME it on the video.
As I stated, that's what I suspicion is occurring.
The 'video' had nothing to do with the Cairo protests either.
