One key party who will not be in attendance Friday at Joint Base Elmendorf-Richardson in Anchorage, Alaska, is Ukrainian President Volodymyr Zelenskyy. Trump said Thursday during a press conference that he hopes the summit will lead to a second meeting that would include Zelenskyy.

The Trump administration "is making quite an energetic and sincere effort, in my opinion, to stop hostilities, to stop the crisis and to reach an agreement that is of interest to all those involved in this conflict," Putin said during a meeting of his top officials to prepare for the Alaska summit, according to a readout published by the Kremlin.
