They’re enraged that Trump and his team didn’t fall for their shenanigans and fire Mueller. LOL. Not just the Rats unless one considers an NT to be a Rat, which is what they are in reality.
They’ve been baiting Trump for a long time....it took him awhile to understand they hide their true intentions....I think Trump had hoped they’d want to do what was good for the country, and it took everyone awhile to realize how diabolical they were going to show themselves as. I often wondered if Trump doesn’t give them a rope to run with for a time on purpose.
