Hillary should just watch the video of her standing in front of the coffins, saying that the attack was because of a film, lying to the families and the nation. See at 1:04 in the video:
Video of return of Benghazi victims
Maybe then she could recall what she actually said.
The title of the link should be "Hillary blamed the Benghazi attacks on a video at min 1:04"
In all the slanging back and forth concision matters.
