U.S. President Donald Trump says he has called Russian President Vladimir Putin and begun to arrange a meeting between Putin and Ukrainian President Volodymyr Zelenskyy, a critical step toward bringing a possible end to Russia's war on Ukraine.

President Trump, Ukrainian President Volodymyr Zelensky and key European leaders met at the White House on Monday afternoon to discuss Russia's war in Ukraine.

President Trump, who for years has balked at American support for Ukraine, has pledged to bring an end to the war. But no deal was reached after he spoke with the Russian leader for nearly three hours Friday.
