Keith Kellogg, the US special envoy for Ukraine, is expected to resign in January 2026 due to Senate confirmation requirements for envoys serving beyond 360 days.His departure raises concerns in Kyiv as US support diminishes amid diplomatic pressures for Ukraine to accept a Washington-proposed framework that could require territorial concessions and military reductions.No successor has been announced, and the diplomatic situation remains precarious with Julie Fisher serving as Chargé d'Affaires.
