WASHINGTON/LONDON/PARIS (Reuters) -- U.S. President Donald Trump and Ukrainian President Volodymyr Zelenskyy clashed again on Wednesday on efforts to end the three-year-old war in Ukraine, with the U.S. leader chiding Zelensky for refusing to recognize Russia's occupation of Crimea.
Trump's Vice President JD Vance said it was time for Russia and Ukraine to either agree to a U.S. peace proposal "or for the United States to walk away from this process," echoing a warning from Trump last week.
