"No material marked classified on my server"
30k emails and only ONE had part of classification mark left in it. And it doesn't appear the classified fact itself was with it; just the marker (although the Bureau's language is vague on that). That's not a bad record. She should have said "don't recall seeing any", CYA language.
"I handed over all work related emails"
There's no evidence she intentionally skipped over some. The "recreated" ones not handed over with the original set appear to have been missed because the lawyers who helped her filter them did a quick-and-sloppy reading job, scanning only the intro. There was nothing in the content of these "missed" emails to suggest they were hidden/removed to hide the content. The missed ones were boring and generic.
It appears to be good old fashioned rush-jobs and slop. Not a conspiracy to hide stuff nor lie.
"No material on my email that was classified at the time"
There's no evidence she knowingly received classified material. Again, she should have used CYA language and used the word "knowingly".
While working there, she should have also put in extra staff in place to monitor and verify classification compliance. Even if they couldn't work quick enough to keep up with rush-job projects, at least they could catch mistakes closer to the point of error and reprimand the offenders to reduce repeats.
She's a Type-A boss and probably pushed staff a bit harder than normal.
As far as CYA mistakes, she made similar per Benghazi when conveying the intelligence of the moment by not using words like "probably is" or "probably not", or "the best indication is that it was caused by an X", etc. Again, missing CYA language.
I don't know why she excludes standard CYA language. Perhaps she's often been accused of "acting too lawyerly" and compensates by making definitive statements. The cure is worse than the disease, though.
