Following common sense here, her decision to ignore State Department regulations (which she lied about) and participate in classified communications (which she also lied about) on a private server immediately after she had made efforts to minimize public access to her communications, leads to the obvious conclusion that she put secrecy above transparency. If her narrative in private testimony matches the public one, then she likely perjured herself as well on the point of whether the State Department authorized the server, since they now say they did not (which again, she lied about).
