As we get closer to Trump’s likely indictment on removing and retaining national security documents from the White House, it is important to make a distinction between his mishandling of classified material and that of Hillary Clinton. 

In her case, Clinton wrote about subjects in private emails that were later determined to be classified.  And she did this on her private server which was outside government control and recording.  However, she fully cooperated with the investigation and provided thousands of emails for review.  Of those, 110 email trails broached subjects later determined to be Top Secret 22 times and Secret 65 times. 

She never took or attempted to email a classified document and never violated Special Access protocols.  Some emails had been deleted, which she had directed as a routine clean-up before the investigation, but many were recovered. What she did was wrong, but the FBI adjudicated it was not criminal.
 Trump on the other hand took hundreds of classified documents, including those clearly marked as Special Access, Top Secret, Secret, and Confidential when he left the White House.  Multiple requests from the National Archives to return them were ignored. 

Subpoenas were ignored, and his attorneys lied that all classified documents had been returned by June.  184 classified documents were discovered and returned from Mara-a-Lago in January, another 38 were returned in June, and the search by warrant in August yielded an additional 18 Top Secret / SCI and 54 Secret documents.  In addition, there were 4 dozen empty folders marked classified which is especially disconcerting.
 
There are multiple criminal statutes that Trump may be charged under (which don’t even require the documents be classified), but the investigation must still determine the full chain of events and assess Trump’s intent in these acts.
