I think Hillary needs to be beaten over the head with this. "Senator Clinton do you have a comment on this?", "Would Berger be part of your administration?" "Do you rely on his advice?"
The real problem seems to be far too many with access to classified info and/or staffers given classified info with no need to know getting access to said. I believe we had SOG teams and hatchet forces cut to ribbons on the LZ or immediate vicinity due to leaks of the same classification that Berger got a mere slap on the wrist for.
