I agree that a president can be tried for treason or malfeasance.
I recall when Hussein was elected the conversation was whether he could pass a security check, and the answer was that he did not have to because he was an elected official.
Like I mentioned before, the president is the commander in chief of the armed forces which includes all of the mentioned components of the below section taken from the pertinent instruction.
DoD Instruction 5200.02 applies to OSD, the Military Departments, the Office of the Chairman of the Joint Chiefs of Staff and the Joint Staff, the Combatant Commands, the Office of the Inspector General of the DoD, the Defense Agencies, the DoD Field Activities, and all other organizational entities within the DoD (hereinafter referred to collectively as the “DoD Components”).
Sections G and H under policy standards reviewed and re-affirmed in 2014 read as follows:
g. No person shall be deemed to be eligible for a national security position merely by reason of Federal service or contracting, licensee, certificate holder, or grantee status, or as a matter of right or privilege, or as a result of any particular title, rank, position, or affiliation.
h. No person shall be appointed or assigned to a national security position when an unfavorable personnel security determination has been rendered.
Being elected president would fall under the title, rank, position part of the entries or as commander of all of the components. Besides, what good does it do to have a need for COMSEC and implement it if the person in charge is not required to stay within its boundaries ?
You didn’t mention where you got the information about his lack of a security clearance, but I can promise you he got one and it was completed before he got elected. We don’t crown kings or queens, we “hire” people to become government officials either by election or appointment. And they must fit the guidelines established with the job requirement. And meeting top secret or higher is one of them for his position.
