When I worked with classified material for 25 years, “C” stood for “CONFIDENTIAL,” not classified.
So when she said nothing was marked “classified”, she was actually telling the truth! It was marked with any of the classified categories, but not the literal word “classified.”
And no one challenged her parsing, nor her intent to circumvent safe handling of classified information. And now we learn she “lost” a couple of phones, and transmitted classified info after leaving the SOS position! Lock Her Up!
