The bottom line is, that was not his job or why he was appointed, you still seem to miss the fact that there was no named, (by information, or evidence) crime to be investigated or to pursue to indictment. Impeachment does, constitutionally require crime(s), the clown still presented none.
I have previously stated in this forum, (which can be searched and found) that we live in an unconstitutional America, I restate it again.
The fact is, ALL grand jury testimony is secret, for good reason, it is a protection, granted by the constitution fourth amendment rights, to the target of the grand jury.
No prosecution, the testimony and procedure is to die, fourth amendment guarantee.
It has not in this instance, it is political now. The fact is, pertaining to Trump, or any president, you can't indict, but you can show enough evidence of criminal acts to initiate impeachment proceedings. I tell the democrats, proceed at your own peril. I personally don't give a sht.
You have no idea of the complete jackasses that have or currently practice law. I have done well, most everything is a negotiation, not really that tough, and you said I can't, I can ..... maybe. Not to boast, not a claim beyond being a complete jackass.
