WASHINGTON, November 29. /TASS/. Andrey Yermak, a former chief of staff of Ukraine’s Vladimir Zelensky, announced several hours later after his resignation that he was ready to head to the battlefront, the New York Post reported.

"I’m going to the front and am prepared for any reprisals… I am an honest and decent person," Yermak told the US-based daily in a text message.

"I don’t want to create problems for Zelensky; I’m going to the front," the daily quoted Yermak as saying without specifying when the former Ukrainian senior state official intended to arrive at the frontline.

On November 10, the National Anti-Corruption Bureau of Ukraine (NABU) and the Specialized Anti-Corruption Prosecutor's Office (SAPO), both independent from Zelensky’s office, announced an investigation into a major corruption scheme in the energy sector, dubbed Operation Midas.

Searches were conducted at the Energoatom energy company and the residences of entrepreneur Timur Mindich and the now suspended Justice Minister German Galushchenko, who served as the country’s energy minister at the time of the events that are being looked into. The investigation found that participants in the scheme had laundered around $100 mln.
