Ukrainian President Volodymyr Zelenskyy’s former chief of staff said that he would go to the frontline and fight for Ukraine after being embroiled in a corruption scandal.

Andriy Yermak, who was abruptly fired on Friday hours after his home was raided by the national anti-corruption watchdog, told the New York Post that he was going to fight for his country, the U.S. tabloid reported late Friday.

“I’ve been desecrated, and my dignity hasn’t been protected,” Yermak told the outlet. “Therefore, I don’t want to create problems for Zelenskyy; I’m going to the front.”

Yermak’s ouster came after Ukrainian anti-corruption agencies revealed that people close to Zelenskyy were involved in a plot to skim around $100 million from Ukraine’s energy sector. No charges have been brought yet against Yermak, a long-time Zelenskyy confidant who was seen as the second-most powerful man in the Ukrainian government.

The former adviser had been a key bridge to Ukraine’s Western allies and had led negotiations with Donald Trump’s White House. In his place, Zelenskyy has appointed Rustem Umerov, secretary of Ukraine’s National Security and Defense Council, to lead talks with top American officials scheduled for Sunday.

Yermak was scathing in his message that he would go fight for his country: “I’m disgusted by the filth directed at me, and even more disgusted by the lack of support from those who know the truth.”

“Maybe we’ll see each other again. Glory to Ukraine,” the former powerbroker added in his signoff.
