Then why was it even brought before a GJ?
Look, I have no desire to do anything that helps Trump in any way. However the general principle shouldn't be thrown out to score some momentary political victory. I'd enthusiastically support changes to the Special Counsel law to specifically authorize release of GJ testimony to Congress with appropriate safeguards for privacy and such. I'd enthusiastically support creating a separate process for investigating the POTUS that specifically address some of the constraints posed by separation of powers concerns and the "unitary executive" theory. However I don't believe and see no one who has presented a credible case why the Grand Jury testimony in this case is the single piece of missing information that is absolutely required to impeach the president or remove him from office if he was impeached. It's simply a Hail Mary attempt to get something, anything to make Trump look bad for a cycle or two (as if he needs the help). If Congress truly feels there is something in there which they absolutely cannot do their oversight jobs without, then they can make accommodations for the privacy and other concerns. For example, the GJ testimony is completely sanitized of any and all information which identifies or could potentially identify a grand jury member. And that they are allowed access to only physical copies in a controlled SCIF facility instead of electronic copies which would be leaked in milliseconds after receipt. Et cetera.
Evidence was brought before the grand jury as part of the overall investigation, it was not a 'Trump grand jury'.
