President Trump needs to stop his tirade over the lies of his former staff. He is implicating himself in knowledge of those lies.
I do not believe he is stupidly putting this mess out there. I believe to his way of thinking, since he knew Flynn lied, as President, he can control that outcome through his own actions regardless of the lies. He is putting out an image of a man in control of the Oval Office regardless of lies by Flynn.
Donald Trump believes himself omnipotent in his ability to handle power. He knows all, sees all and thinks all. The country has never been safer, you see.
