Not so surprising is moscow mitch was personally responsible for getting the bill passed if not actually being the author of the bills to allow unlimited amounts of donations to pacs. I believe it was his 'companies are people too". Right after he did that, mitch took in millions from russian funded sources as well as money for the russian backed aluminum plants he sponsored just a few years ago.
Moscow mitch was also personally responsible for getting those companies back into the states after breaking the sanctions against the russian mob parties from having plants here. Over 250 senators had voted to keep the mobs sanctioned and mitch voted against it and used a filibuster to do so.
Mitch uses the filibuster whenever it benefits him and then tells others it isn't fair when used against him.
