court. could michael cohen enforce that? probably not. in fact, off the top of my head, i can't think of a way that he could enforce it. but the government can enforce it. and they could do it by charging people with a whole variety of crimes. from the ones you and i have already discussed to possibly obstruction of justice if they can show the reason for these leaks were to hinder the investigation, undermine the prosecution or try. and again i think it would only be a try, not a success. try to undermine the value of michael cohen as a witness. look, if he really knows this stuff, rachel, he's a valuable witness. leaking the information is not ideal, but they're still going to need mr. cohen. >> former u.s. attorney, former senior fbi and justice department official ringing clear as a bell tonight. che thank you very much. >> my pleasure. >> it is five minutes before the top of the hour. we will have more on this
