I agree with your premise that there is dirt on both sides, but... There aren't a lot of people in Congress, or DC for that matter, that were in office, had power, etc. when the Soviet Union collapsed and in the direct aftermath of it. That was what, about 30 years ago? There were some, sure, but I don't think there were all that many. They would have to be what, about 45 at the oldest to be there and be really involved then.
