WASHINGTON (Reuters) - U.S. President Donald Trump will meet with a senior North Korean envoy on Friday, the White House said, as efforts continued to get a U.S.-North Korean summit initially planned for this month back on track.

Kim Yong Chol, who was previously blacklisted by the United States because of his role in his country’s military establishment, was expected to hand deliver a letter from North Korean leader Kim Jong Un to Trump.
