I'm starting to wonder if they aren't getting ready to dump all the blame for Benghazi on her to protect Obama. She has enough dirt on him for it to get really messy if she doesn't go along, so part of the deal is that she gets a Presidential pardon on any criminal charges. But for that to work, she'll have to be convicted before he leaves office. He can't grant a pardon for crimes she hasn't been convicted of yet so they need to get in front of it and keep it steered in the right direction.
That's exactly what Ford did for Nixon.
