Hillary would want to have someone the libs publicly encourage her to come forward so she could say that's what convinced here to do it, but she could move without that if she was sure there would be at least some lefty media in her corner. Without that, I doubt she comes forward until after the election unless the polls get even worse Barry than they already are in which case she may go ahead no matter what.
Barry is the first person to ever cross the Clinton crowd and walk away unharmed and you know they'd love to be the deciding factor in keeping him from having a second term. They're going to be the last ones standing after a King Barry defeat anyway, though, so they'll want media in their corner to put the best face on everything. Even without it, though, you know Bill sees this as he and Hillary's chance to start taking back control of the party that's now in the hands of the coffee fetching types Barry has planted everywhere.
Let one more little thing happen on the international scene in the next week, though, and she and Bill will be together in front of cameras in a heartbeat spilling the beans on more than just Benghazi. She'll have plenty of solid information on how Benghazi is just the last straw, not the only straw.
