Trump's possesion of those documents outside an approved, secure facility is inappropriate, irresponsible, and careless, if not a crime.
When a document has a classification marking on it, there are policies, procedures, and rules, if not laws, on their handling and storage.
Trump is owed due process to determine if what he did rises to the level of a crime.
Those documents are property of the United States Government, not the former President.
I am not comfortable with the rhetorical argument that a President can summarily declassify sensitive materials on a whim.
Our system is one of checks and balances, in which no single person has absolute authority.
The United States Constitution is a repudiation of the Divine Right of Kings and European monarchies of the time. Defenders of the Former President have argued that the Presidency is an absolute Executive. This is dangerous. The United States has been backsliding towards an Imperial Presidency because Congress has subordinated itself to the Executive Branch. Executive Orders and Supreme Court Precedents are not appropriate substitutes for proper legislation.
It was a mistake for Jim Comey to not prosecute Hillary Clinton. His mistake set the unfortunate precedent that high-ranking members of the Executive Branch are not subject to the policies, procedures, rules, and laws governing the handling and storage of Sensitive materials, like all other Government personnel and approved contractors.
There is insufficient evidence to escalate the charge of a crime to Treason, or anything else at that level.
The former President simply mishandled classified materials and took unauthorized possession of Government Property.
,
What the Former President did, and how he mishandled Government Property was wrong. Whether it rises to a level beyond violations of Administrative Law, policies, procedures, and rules is beyond my ability to judge.
But again, what was the Former President's motivations for unauthorized possession of Classified and Sensitive Government Property?
If it is determined by the Courts, that the President has the summary, absolute authority to declassify sensitive Government materials, without following a prescribed declassification process, our American Experiment is over and a failure.
