Donald Trump very likely controls his own Twitter account, personally, with very little input from staff before hitting submit.

This is contrary to other public figures, such as Barack Obama, who had communications staff manage his Twitter account.

Part of Donald Trump’s “draw” if you will is that his messaging is nearly completely unfiltered, raw, and as close to his stream of thought as anyone has ever likely seen from a President in the modern era.

As for how dangerous that is, I’m sure people will be discussing that for years to come.

Probably the only way to enforce this is a constitutional reform or a law (or an executive order :) ).

You think Donald Trump gives a shit about protocol? And who exactly would enforce it?
