Actual anti-corruption operation or internal power struggle?

NABU has exceeded their mandate, this kind of investigation is not who we are. They are truely treasonous russians just as the President said in January.
They even said American Entrepreneurs (not oligarchs, that's Russia and NABU) were involved in stealing from Ukraines brave Atomic Power!
Jail NABU now, Save the President and the brave soliders fighting Russia from this conspiracy!

Who's directing the hohol anti-corruption agency, NABU, again't Zelesnky's buddies?
is this Bundanov making his play for the hohol throne?
