Probably the most honorable Republican in the Party, Mueller is defending the Constitution, and doing it brilliantly.
Trumpanzees are shitting themselves (as is the Orange Turd), because they know well that the axe is about to fall.
Don't forget, Collusion is just a part of Mueller's brief. He's also charged with investigating
"...any matters that arose or may arise directly from the investigation."
and the Trump dynasty is an incredibly rich field of malfeasance.
They're looking at money-laundering on a massive scale, lying under oath to just about everyone, Obstruction of Justice by the 'President', and a myriad other offences.
There's a blood-bath coming, brace y'self!
