While trying to find background on Liam Donovan (who doesn't have much of an Internet footprint), I came across other non-Kim Iversen sources claiming the indictment specifically mentions Chen & Donovan openly referring to "the Russians".

Fwiw, I like Chen and don't really care that much about Russian funding.

The case does really hinge though, in the court of public opinion at least, if she knowingly and surreptitiously accepted Russian monies.
