Trump and Vance clash with Zelenskyy over gratitude

President Donald Trump and Vice President JD Vance had a tense exchange with Ukrainian President Volodymyr Zelenskyy in the Oval Office. They accused Zelenskyy of lacking gratitude for U.S. support amid the ongoing war in Ukraine. The argument escalated when Zelenskyy challenged Vance on U.S. diplomacy with Russia. Trump and Vance insisted that Zelenskyy should be more appreciative of American military aid, while Zelenskyy defended Ukraine's position and the need for guarantees in any ceasefire. The confrontation led to the cancellation of Zelenskyy's remaining White House visit. It raised questions about the future of U.S. support for Ukraine in its conflict with Russia.
