I'm sure she had plenty of conversations with the president and others in the state dept.... So did Colin Powell using his private SECURE server.We just have to take her word that she never transmitted classified information on her server. No discussions with the president (classified), no talking about her schedule (classified), nothing to do with private discussions with foreign dignitaries (classified).
Did she ever do her job, or was she just greasing everyone for donations? Nigeria paid her foundation half a billion. I wonder what they expected in return?
