Reuters reported the information.Keith Kellogg, President Donald Trump's Special Envoy for Ukraine, plans to step down from his position in January, according to four sources who spoke on condition of anonymity. The retired lieutenant general's exit would eliminate a crucial voice supporting Ukraine within an administration that has increasingly pressured Kyiv to make concessions to Russia.Kellogg's departure comes at a particularly challenging time for Ukraine. Sources revealed Wednesday that the U.S. has presented Ukrainian President Volodymyr Zelenskyy with a framework for ending the war that would require Ukraine to surrender territory and reduce its military capabilities. The proposal, drafted by U.S. Special Envoy for Peace Missions Steve Witkoff, represents a significant shift toward accommodating Russian demands.The timing of Kellogg's exit appears tied to federal regulations requiring special presidential envoys to receive Senate confirmation to remain in their posts beyond 360 days. Sources indicated that January represents a natural departure point given these legislative requirements.European diplomats and Ukrainian officials had viewed Kellogg as a sympathetic advocate who consistently condemned Russian attacks on civilian infrastructure - a stance that sometimes put him at odds with other Trump administration officials. His clashes with Witkoff were particularly notable, as the peace envoy has echoed some of Vladimir Putin's talking points and advocated for territorial swaps favoring Russia.Among Kellogg's diplomatic achievements was securing the release of dozens of hostages held by Belarusian leader Alexander Lukashenko in exchange for limited sanctions relief.Trump's approach to the Ukraine war has shifted repeatedly since taking office. While initially pushing for an immediate ceasefire, he abandoned that position after meeting Putin in Alaska last August, only to embrace the ceasefire concept again following his October meeting with Zelenskyy in Washington.The administration has sent mixed signals on Ukraine support, briefly cutting intelligence sharing in March before resuming and later expanding it. Trump established a program allowing European allies to purchase U.S. weapons for Ukraine while largely ending direct military assistance programs initiated under former President Joe Biden.Currently, a U.S. delegation led by Army Secretary Dan Driscoll is conducting a "fact-finding mission" in Kyiv, with plans to meet Zelenskyy on Thursday.It remains unclear who might replace Kellogg in the role. The United States has yet to appoint a Senate-confirmed ambassador to Ukraine, with career diplomat Julie Fisher serving as charge d'affaires since May.
