Donald Trump has said repeatedly he could settle the war between Russia and Ukraine in one day if he's elected president again. Russia's United Nations ambassador says he can't. When asked to respond to the claim from the presumptive Republican nominee, Vassily Nebenzia told reporters Monday that "the Ukrainian crisis cannot be solved in one day."

At a CNN town hall in May 2023, Trump said: "They're dying, Russians and Ukrainians. I want them to stop dying. And I'll have that done " I'll have that done in 24 hours." He said that would happen after he met with Ukrainian President Volodymyr Zelenskyy and Russian President Vladimir Putin. And he keeps repeating the claim on the campaign trail.
