what the full scope of the evidence. when it comes to flip, we still don't know fully who he has cooperated against, how many people he is cooperating against, what his information. so it is like an iceberg where you only see the tip. and it's not until the cases are brought and tried that the public will get to see all the information. >> and garrett, you also make the moan point we don't know if mueller is done with manafort, whether he'll bring additional charges, whether there will be any plea deal. how much do you think we'll learn from manafort's trial which as anne said starts tomorrow in virginia? >> we're going learn a lot. and the other thing is paul manafort is going to learn a lot. i mean, he's almost 70 years old. he is already in jail for witness tampering during the course of the trial preparation, staring at potentially as many as 300 years in federal prison. it's not going take a lot for him to be staring down a life sentence if this trial begins to go poorly. so i think the big thing to watch is how paul manafort thinks his own trial is going and does he think at some point over the next couple of days
