U.S. Ambassador to Ukraine Geoffrey Pyatt objects to the idea of replacing technocratic government ministers in Ukraine with politicians.

"Dangerous voices saying 'We've had enough of technocratic ministers & professional governance; it's time for politicians to take reins'," Pyatt said on Twitter on Tuesday.

"Would be enormous mistake, fuel Kremlin effort to mischaracterize UA [Ukraine] as failing instead of as emerging democracy," Pyatt said.
