Mitch McConnell received $3.5M In Campaign Donations From Russian Oligarch-Linked Firm.
Not surprisingly, another Russian oligarch enjoyed McConnell's efforts to block continuing sanctions.
McConnell is tied to dirty Russian oligarch money the same way that Trump is, so in order to take down Trump, one must take down his "human shield" in the Senate.
Thats all fine and good,
BUT THE BOTTOM LINE: POLITICAL BIAS WAS NOT A FACTOR.
