A lawyer has a personal and fiduciary duty to his client. An ethical attorney would never advise his client to break the law.
If Cohen performed illegal acts, it certainly wasn’t at Trump’s instigation. He did them of his own volition.
Cohen’s downfall came about because he believed he was above the law and he would never be caught,
That doesn’t make it Trump’s fault.
If he talked to the Prosecutors, he is not a good lawyer. Every lawyer I knew in Tampa, Florida advised not to talk with the police. He has shown himself to be a cry baby, along with being a liar, too. Whatever one thinks of Corsi and Stone, they are facing the music like men up to now.
