Any new charges would have to presented to the House, and be acted upon there.
If they are not in the articles before the Senate, they’re dead in this proceeding.
If anyone disagrees with that, speak up. That’s how I understand it, but I could be wrong.
When I say moles willing to fabricate charges, those would be charges that would support the current presented articles (e.g., Bolton). That's the advantage when you can fabricate out of whole cloth, behind these ridiculous (as being currently applied) whistleblower protections.
Watch and learn what the masters of smoke-and-mirrors "break" over the weekend.
I hope I'm wrong, and that Bolton was their Plan B. But I suspect they learned from the Kavanaugh hearings, and came prepared with a Plan C.
