His “testimony” will be about one thing: blaming everyone else around him.
People like him don’t testify. They just want to deflect and divert attention away from themselves.
He seems a bit late to the immunity game and so many of the lower level key players have already spilled their guts it's hard to see how much he could add.
He could provide devastating testimony against Comey, the DOJ and many Obama Administration scandals.
Don't think ol’ Andy is going to do well in general lockup at a Federal Prison so you never can tell what he might use to bargain with for avoiding a long stay at Club Fed.
The Clinton and Obama people must be thinking the same thing right about now.
