That press statement by Moscow Mitch is outright BS…the guy must have 1984 memorized, it’s infuriating how much he does stuff like this. Odds are he waited as long as he could get away with before letting this through, so that the chances of really useful changes are going to go into effect are smaller.
ETA: If the whistleblower stuff is through Ukraine as the rumors suggest, then it is interesting that McConnell may be reacting to that with this package. The Giuliani-Ukraine tactic to interfere with the election by hurting Biden may have gone further than we thought, and Moscow Mitch may be trying to make it look like Republicans really are trying to protect elections, it’s just Trump doing dirty deeds. That would be followed by pitching Trump overboard and chaos in selecting a new candidate, so Mitch is trying to save the Senate by pulling this stunt. Hopefully it backfires, it’s a craven move on his part if that’s what he’s thinking.
