President Donald Trump's senior aides and allies criticized Ukrainian leader Volodymyr Zelenskyy during a European summit in London, where he sought international support against the Russian invasion. White House officials and Republicans urged Zelenskyy to show more gratitude for U.S. support and consider concessions to Russian President Vladimir Putin.
Following a contentious Oval Office meeting, concerns were raised about the future of the U.S.-Ukraine relationship. White House national security adviser expressed disappointment in Zelenskyy's behavior, suggesting he lacked readiness to negotiate an end to the war. The possibility of territorial concessions from Ukraine and Russian security guarantees were mentioned as potential negotiation points.
