U.S. President Donald Trump said his talks with Russian President Vladimir Putin were "extremely productive,” noting that the two leaders reached agreement on many issues and left only a handful unresolved. Trump described one of the remaining matters as “probably the most significant,” but expressed confidence that it, too, could be settled. The president offered no further details on the topics discussed or the areas of agreement, reiterating only that substantial progress had been made. Putin did not immediately comment on the outcome of the meeting.
