The weekly standard had a sensationally titled piece that was picked up and linked to by the Drudge report that claimed it was proof that Hillary Clinton knew she sent classified info over her personal email, which would be a violation of federal regulations regarding the handling of classified information by government officials and employees.
The article includes this image:
However it appears the content of the email was officially classified on 30 July 2015, quite a ways after the original claim that Hillary never sent classified information. However it is possible that the reason for the official classification was that the content was something that should always have been considered classified.
So the question is, What does reason 1.4(B) and 1.4(D) in the confidential reason memo mean?
