Zelensky chief of staff Andriy Yermak resigns amid $100M probe; questions over U.S.-backed peace talks

Andriy Yermak resigned as President Volodymyr Zelensky’s chief of staff after anti‑corruption agents from NABU and SAPO searched his Kyiv apartment inside the presidential compound and reportedly his office in a probe dubbed Operation Midas — a 15‑month, roughly $100 million embezzlement investigation — with Yermak saying he has not been formally accused, is cooperating and that investigators “faced no obstacles,” while Zelensky accepted the resignation to “avoid rumors and speculation” and announced a forthcoming reshuffle. The departure casts doubt on recent U.S.–Ukraine–Europe peace talks — Yermak led Ukraine’s negotiating team in Geneva and was due to meet U.S. envoys in Miami — and officials warn the scandal could weaken Kyiv’s negotiating position even as EU and U.S. partners watch closely.

📌 Key Facts

  • Ukraine’s anti‑corruption agencies NABU and SAPO searched Chief of Staff Andriy Yermak’s apartment inside the presidential compound and carried out searches related to his office on Friday; media reported the office search though investigators declined to confirm details, and Yermak had been in Geneva negotiating peace talks that weekend.
  • Andriy Yermak resigned as presidential chief of staff on Friday; President Zelensky accepted the resignation in a video, saying he did so to “avoid rumors and speculation,” thanking Yermak for representing Ukraine in negotiations and pledging to reshuffle the president’s office and name a successor while urging unity.
  • The actions are linked to “Operation Midas,” described as a 15‑month, $100 million embezzlement probe in the energy/nuclear sector involving about 1,000 hours of wiretaps; investigators have removed two cabinet ministers this month and other officials have been investigated, though Yermak has not been officially named as a suspect.
  • Investigators suspect Tymur Mindich, a onetime business partner of Zelensky, as an alleged mastermind of the scheme; Mindich has fled Ukraine and would likely be tried in absentia if charged.
  • Yermak said investigators “face no obstacles” and that he is cooperating with lawyers present; his spokesperson said he has not received a formal notice of suspicion and has not been told what the searches specifically concern.
  • The probe and Yermak’s departure raise questions about U.S.‑backed diplomatic efforts: Yermak led Ukraine’s team at recent U.S.–Ukraine–Europe talks in Geneva, the peace framework discussed was pared from 28 to 19 points after Geneva, and Yermak was due to travel to Miami to meet Trump envoys Steve Witkoff and Jared Kushner before they planned to travel to Moscow — a U.S. official warned the scandal could weaken Ukraine’s negotiating position.
  • The EU is following the developments closely; an EU Commission spokesperson framed the searches as evidence Ukraine’s anti‑corruption agencies are functioning and linked that to progress on EU accession.
