Re: "the issue has reached the highest levels of government"
I think the real issue is that when he won the election, Trump couldn't really believe it
He probably spent the first few weeks thinking the Secret Service would burst in at any moment and tell him to piss off because the real president wants his office back.
Since they didn't throw him out he just keeps tweeting whatever comes into his head after the latest Whitehouse briefing so that he looks like he's doing something.
