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 he hopes the summit will lead to a second meeting that would include Zelenskyy.

American officials quickly discovered a major snag in planning for the summit: summertime is peak tourist season in Alaska, and options both available and equipped to host the two world leaders were severely limited.
