Honestly, while I do hope the twitter storm today is due to Mueller dropping some more bombs, I really just think it's his narcissism getting in the way again. With what I would assume most of DC and the (fake!) media focusing their attention today on McCain's funeral, Trump is feeling that the spotlight isn't on him right now where he wants it to be. You have praise for McCain coming from both sides of the aisle (and even the media) - a man that is everything Trump is not being praised. This is Trump's worst nightmare.
