Rustem Umerov, Ukraine's chief peace negotiator, held secret meetings in the U.S. with FBI Director Kash Patel, Deputy Director Dan Bongino, and Donald Trump's envoy Steve Witkoff, sparking concerns among Western officials about ongoing peace negotiations.These clandestine discussions, occurring amid a U.S. pressure campaign, reportedly involve Umerov seeking amnesty or the U.S. pushing for significant Ukrainian territorial concessions, with Trump reportedly setting a deadline for a deal.Concerns about Umerov's potential corruption and a $100 million misappropriation from the energy sector led to Andriy Yermak's resignation, though the White House downplayed the significance of the diplomatic engagements.Umerov was appointed to lead Ukraine's negotiating team last month.
