Cohen is either going to jail for a long time or will flip on Trump.
He has been Trump's fixer. He is a thug. Much of what will put him in jail he did without Trump's involvement but he has lots of dirt on Trump, he can use to lessen his sentence.
They have a lot of dirt on Cohen.....enough to put him away for years
As Trumps fixer, he has much more damaging information on Trump than Stormy Daniels
If as the dossier states that Cohen did go to Prague to meet with the Russians to teach them how to hide the money path for them paying the email hackers for their theft...and to clean up any other Russian connections, then Cohen squealing could be valuable information in understanding all that was done by the Russians and the collusion...
But it could be Cohen knows more about the way Trump has been able to buy his last few big real estate deals with $400 million a pop, IN CASH...
are the Putin friendly Oligarch's funding him, like his two sons had revealed? AND WHAT Trump is giving them in return?
IF there is no Trump promising something in return, there is no illegality in the Oligarchs funding him, though it may be very unethical or sleazy in some way....and he hid it from the American citizens about his business Russian connections, but not illegal....just slimy...
so many unknowns on all of this.....
