Sawyer hammered her, yes, but at the same time, she almost seemed to be ... PLEADING ... with Clinton to take the responsibility, actively trying to make her look better as a candidate.
It was almost like “I’m HANDING you this opportunity you stupid, arrogant ass, why aren’t you jumping on it?”
Sawyer was more angry at her not taking the cue and acting her part, rather than genuinely PO’d about evading a responsibility that was clearly in Clinton’s court.
That was my impression of it, anyway..
Obviously, Sawyer already had a talking point for Clinton. Sawyer was going to spin the response to something like Clinton tried to do something, but it was not enough and she feels bad. Sawyer knows that the Benghazi incident is a mill stone that must be cut from that stumbling drunk's neck.
