The White House says it’s preparing for a second possible meeting between President Trump and North Korean leader Kim Jong-un, after Trump received a “very warm, very positive” letter from Kim requesting another meeting. Trump and Kim met for a summit in Singapore in June, marking the first time a U.S. president has met with a North Korean leader. Meanwhile, South Korean President Moon Jae-in is slated to hold his third summit with Kim next week, as the two leaders continue discussing plans to formally end the 1950-1953 Korean War.
