people from cooperating in my opinion is obstruction. these e-mails look potentially explosive. as shan said, they use code language. they talk about establishing a back channel. those are things we saw in mob cases quite a bit. that said, they remain ambigue s. i think this middle man communicating between cohen and rudy giuliani, they have this other story which is i don't find it particularly plausible but it is possible that cohen was just worried that the president was mad at him and all that is being communicated is don't worry, the boss loves you, he is not mad at you. which version do i think is more credible? i think it is the pardon scenario but it is not impossible that is the other way. >> what warren buffett said, if you don't want it on the front page of a newspaper, don't write it at all. thanks very much.
