Gawd, It was determined early on that collusion isn't even a crime. The entire collusion conspiracy was kept alive through our insane President daily spouting, "no collusion" for months on end. Virtually everyone on the left is satisfied with Muellers findings on collusion.
That was not the sole basis for the investigation, but you know that.
The investigation found enough corruption to pay for itself and was basically free, from taxpayer funding.
That should make you happy.
