this ain't political and about whether other people like his criticism. it is about that arc. so cohen could be a big star witness. he's believed to be preparing to testify. he's all but said that publicly. but he has been on both sides of things. take a look. >> i know mr. trump, i've stood by him, shoulder to shoulder for the past decade. >> donald cared for no one or anything other than himself. >> i'm obviously very loyal and very dedicated to mr. trump. >> i'm going to jail. >> i think he's going to be a great president. >> because of my decision to help mr. trump hide that payment. >> that is just some of the back and forth, i'm also curious if you think the lawyers will use any of what we're about to show and remind the audience, he did go to prison for charges reeve lating to deceiving the public and he has pled guilty to lying under oath. would they use this and how? >> oh, sure.
