Just to add a thought. Why, would such a basic and open letter stating the obvious chain of command after a administration change be " CLASSIFIED"? This letter obvious was CLASSIFIED at one point, because if you look at it. It is marked UNCLASSIFIED now.
Does this seem odd or am i just over thinking this. Anyone with better knowledge of such things please educate me.
everything must display the classification that it has as it determines distribution. unclassified simply means that it isn't classifed and can be distributed on unclassified channels like the WWW.
