Ryaboshapka also has started to audit how previous investigations were pursued against the owner of Burisma, the natural gas company that employed former vice president Joe Biden’s son Hunter.

But anti-corruption activists say the audit is unlikely to produce any information that would lead to evidence of wrongdoing on the part of Biden, since no evidence has emerged…

She said Mykola Zlochevsky, the owner of Burisma, “has to be investigated” for alleged self-dealing that predated Hunter Biden’s association with the company, including how Burisma was awarded several extraction licenses while its owner was Ukraine’s natural resources minister from 2010 until 2012.

But a move to prosecute him will be seen by Americans through a political filter, she predicted.

“I cannot imagine anything he can do that would not be interpreted as a political sign by American journalists,” Kaleniuk said, referring to Ryaboshapka. “Any decision will be politically examined.”
