The use of the word "Impeachment" in whatever Democrats now are doing, does not make their activity 'an Impeachment', nor does "Impeachment" authority convey to those doing today's activities. Today's activities are just as they were last week and the weeks prior.
When a formal vote of the House Of Representatives on whether to begin Impeachment Proceedings may occur, if it occurs, with the proceedings may come a variety of things, including Rights of the President's party House Members.
Democrats are attempting to gin up "impeachment" talk in the media, very successfully due to complicit mainstream media, without asking Democrat House Members to commit to anything, and avoiding the spectacle of Democrats voting against their Constituent's interests in many cases.
At this point, a few Committee Chairs, from solid BLUE cities and locations, and Speaker Pelosi, take any risk, and their constituents, their Districts, are solid blue, will vote for them whether they are on the ballot or not. 6 House Members?
The rest of the Nation are unrepresented in this dust up, wholly, no matter who their representatives or where they may live, or what they believe. This handful of zealots, and sycophant mainstream media, and the comedy echo chamber, are running what amounts to a coup to topple the President, drive his approval numbers to a tipping point, the truth be damned.
