Cohen was never a Trump supporter.
As his attorney he secretly recorded their conversations.
He then presented perjured testimony against Trump.
Cohen has been shown to have been a liar.
I would hope Flynn, Manafort, Corsi and Stone are pardoned.
Even discounting Cohen, what about the others and the others yet to be targeted? Trump can pardon them but they will be just as bankrupt, just as damaged from jail time, just as unemployable, their families just as scarred. Not acting to stop this inquisition puts the blame for these peoples suffering in the presidents lap.
