Wouldn’t surprise me one bit, for him to be lying.
It won’t make any difference. Trump will not be impeached. And if they try it, I expect a military coup will be the result. Lincoln had a sitting Supreme Court Justice jailed.
Jackson ignored a scotus ruling against him.
We can hope you are right, but I am not sure the military would step in to stop an administrative coup. What needs to be done first is for military police and investigators to raid Mueller's offices along with all of his fellow coup plotters to seize their records, computers, and surveillance recordings that will expose the enemy agents that they are.
