Its all postering for the upcoming election.
If they can keep the focus off POTUS, then they believe he will have a chance for another term.
Frankly, if they would just leave things alone to run the natural course, the truth and hypocrisy will come clear.
Think back a few years ago. One particular Senator in CA had a bull horn shouting to impeach the elected before he took the Oath of Office while encouraging confrontations and mob reactions. Thus started the beginning of the Witch Hunts that are still running today. 8 years of this shinola is ENOUGH.
Its all a huge load of CRAP.
