Trump is a Fake President
It means the American people cannot trust what comes out of his mouth. He has lied about his finances, his business, the people he has grievances with and actual statements he is recorded saying
He lies about things that are easily verified and about stuff that simply doesn't matter like the "you can't get a dress" bullshit. Why lie about something so insignificant? Well, that's what pathological liars do.
The problem with our new President is that his first impulse seems to be to lie
Like you said, he creates facts out of thin air and then throws a temper tantrum to prove they are true
With CNN, he chose to single them out and publically humiliate them when he knew for a fact that he had been briefed on the dossier
I really want to see Trump get through the next four years without a major incident. But I think his character flaw of telling lies is going to come back to haunt him. Brought down Nixon. Destroyed Clintons second term.
Trump will be hounded incessantly once he tells a lie too big to just brush away
