President Donald Trump has lashed out at Ukrainian President Volodymyr Zelenskyy once more. Trump says Zelenskyy is prolonging the ‘killing field’ after the Ukrainian leader pushed back on ceding Crimea to Russia as part of a potential peace plan.

The Biden administration sought evidence of alleged Russian war crimes in Ukraine. The Trump administration is reportedly undoing those efforts.

President Volodymyr Zelenskiy said on Tuesday Ukraine was ready for talks with Russia "in any format" once a ceasefire is set, while the Financial Times reported President Vladimir Putin had offered to halt Russia's invasion at the current front lines.

President Donald Trump ratcheted up pressure on Volodymyr Zelenskiy to accept a peace deal that critics fear will favor Moscow, accusing the Ukrainian president of prolonging the war that’s now in its fourth year.

"This statement is very harmful to the Peace Negotiations with Russia," Trump said in a social media post. He said Crimea was lost years ago "and is not even a point of discussion." Zelenskiy on Tuesday reiterated that Ukraine will not recognize Russia's occupation of the Crimea.

President Donald Trump slammed Ukraine’s President Volodymyr Zelensky on Wednesday for his comments that Ukraine wouldn’t recognize Russian control of Crimea, calling the remarks “very harmful to the Peace Negotiations with Russia.
