Trump could carry out a genocide and not be impeached. It's simply amazing. If Obama had done even 1% of the stuff Trump has done he'd be impeached first, then thrown in Prison, Michelle would be in Prison, Sasha and Malia would be in Prison, Bo would be in little doggy Prison, and all his cabinet would be sent to Guantanamo for treason.
Just get used to it, nothing is going to happen to Trump. If he fired Muller he'd still not be impeached. It's just the way things are.
