The Republicans don't control the house after January, that is the only reason the Republicans care now.
Trump literally swore into office committing impeachable offense and the Republicans went out of their way to avoid looking into them. I want to have all of that looked into and drug into the light and want the Republicans forced to be held accountable for it which will cause many of them to resign or lose any chance of re-election.
And after the Republicans lose the house, they won't be able to pass anything without going through them. So that way of consolidating power will be over. And they can change their rules in the Senate the same either way with or without this happening with their majority till they lose it.
Trust me, I don't want the Republicans in power, I want them held accountable along with Trump.
