If it is a sting that means the illegal alliance is secret..not out in the open
Sting does not prove “illegal alliance”. It’s a Mueller/DOJ sting. Not a Trump sting. Trump even says he has no control of the DOJ - which is why he doesn’t think about firing Mueller - he can’t.
Again “illegal alliance” between Trump/Mueller is your term - your imagination. Why do you insist on defining it that way? Are you a never trumper? What’s your problem?
