Right, or allegedly trying to extort the government of Ukraine to end an investigation against the official's relatives. Corruption on all sides unfortunately.
It seems that in both cases the accused was acquitted or the investigation against them was closed. That's hardly a reasonable indicator of innocence though, as just like you said above, powerful people can often make up excuses to get away with crimes and corruption scot-free. You might be entirely right that one example really happened and the other didn't.
