President Trump is set to meet with Ukrainian President Volodymyr Zelenskyy and European leaders on Monday as the U.S. pursues a peace agreement between Russia and Ukraine.

Trump and Putin met at Joint Base Elmendorf-Richardson in Anchorage, Alaska on Friday afternoon to discuss an end to Russia’s war on Ukraine, which began more than three years ago. The pair announced “great progress” had been made, but they still did not reach any kind of plan to end the war.
