Did Hillary intentionally take Top Secret code word material and hand it over to another person with no security clearance? No, she has only been accused of setting up a system similar to the system used by her two predecessors (which was legal), that may have allowed a very small number of emails to be stored which were later found to have possibly needed to be classified.
