She had a very high security clearance. Note that it does not say that she shouldn’t have had the information - but simply that it should have been “stored under more secure conditions,” probably meaning not on her laptop.
Of course, they all carry these things on their laptops. This is just an excuse for the FBI and others to continue harrassing her. I think she may actually be the one they’re after. She seems to be pretty conservative, and knowingly or not, she may have stumbled on some information that would seriously compromise Obama.
Obama was holding the “affair” - which he and the FBI have known about probably since before Petraeus was appointed - over Petraeus’ head but now Petraeus has done the only thing possible and admitted it. This doesn’t mean that he’s necessarily going to tell the truth about Benghazi in his testimony, though; he lied the first time, and he may lie again to protect himself against perjury.
But Broadwell wasn’t involved and hasn’t testified, so she could be the wild card in this. I wouldn’t be in the least surprised if she is suddenly put into custody on some bizarre and trumped up charge.
Not if they want to avoid jail time. There are very strict rules on the handling of classified information, and copying it to a personal laptop is way, way over that line.
