When my clients are guilty, I tell them not to testify.
So you know your clients are guilty? Why don't you advise them to admit their guilt and do their time? That's the ethical way isn't it?
What is Trump and his administration guilty of?
If my clients were to tell their employees or friends not to testify, the DA would charge my clients with witness tampering.
True; but in this case you have the Constitution working against the Party of the Jackass. We call it Executive privilege. The Constitution does not give the House the right to conduct fishing expeditions to INVENT criminality.
Now, if Schiff and the Party of the Jackass have PROOF that a crime has been committed by Trump and his administration, they can demand an independent counsel to investigate said crime and/or take their case to court to enforce these feckless Congressional demands.
