clum columbia university. i'm not sure where to again. the cohen matters, what are your big take aways from what was discovered today on cohen? >> there's too many to talk a bt about in a period of time. the distinction between the people in my former office in the southern district had towards michael cohen, his veraci veracity, helpfulness and that of mueller. >> mueller thought he had more veracity. >> it was a much kinder and gentler submission. my old office submission is scathing in how they talk about how michael cohen brought this upon himself. he engaged in serious crimes. the fact he was doing this and will forego a pardon does not make him a hero. how he was not complete in his cooperation. the suggestions was unpersuasive to the government.
