Agreed. But mTrump’s lawyers were not forcefully persuing this yesterday, other than to make the point that the 18th witness’ testimony is still being held secret. Schiff stated that he was following committee rules that prohibits release of IG testimony (I bet those rules were created by Pelosi for this Congressional session)
House committee rules have no relevance in the Senate, and certainly have no bearing in a court of law. If the IG testified that he had credible evidence of an assassination conspiracy against Nancy Pelosi, you know damn well that this information would be disclosed.
