"Taken money" is fairly ambiguous. I would think they are waiting for more fallout to sort out what was known and unknown at the time of the contribution. That's only 89% of the SDC, not everyone.
I'm thinking the dems might be dirtier than news reports suggest. They have their shills fanning out to all the yelling head shows in large numbers, and they're more shrill than usual. Usually, that means they're trying to divert attention--in this case, perhaps from themselves.
