The President decides what is classified, not some affirmative action administrative state parasitic bureaucrat.
There are Federal statutes that make it a crime to mishandle or share classified materials, but there is no Federal statute that explicitly defines what constitutes “classified materials.” Instead, the definition of “classified materials” lies entirely within the executive branch of the government. And since the President (by definition) cannot be subject to the authority of personnel in executive branch departments that report to him, he cannot ever be doing something illegal by sharing or publicizing information that had previously been deemed “classified” by his subordinates.
