I agree with an addition.
There is currently an Impeachment inquiry going on. This is not Impeachment. But the Republicans are all in a twist because it's not in public. How many inquiries and/or investigations are conducted in public?
...and of course if it was being conducted in public, they'd be complaining that allegations were being made before definitive proof had been provided.
Of course they really want is for the President's accusers to be named publicly so that their reputations can be destroyed - likely with half-truths an falsehoods.
