Trump literally cannot keep his mouth shut! He can't. He's spent the past 70 years of his life talking and talking, and talking his way out of every form of trouble and crime he's ever gotten himself into and it's worked. Lying, insulting, distracting, controlling the narrative or obfuscating the point are all the tactics he insists on deploying because they've worked his whole life.
If you look closely enough you can see that what he's saying now is the exact same thing he's said every single time he has been caught doing something wrong.
Oh, and watch his hands when he speaks. You can tell he knows when he's lying when he makes those gestures with his hands, an open and close gesture (where he moves his hands close together, than apart, then together repeatedly ) which is a begging imploring gesture for people to believe whatever he's saying in that moment.
