U.S. officials say North Korea has said its leader, Kim Jong-un, will be prepared to discuss denuclearization during a proposed upcoming meeting with President Trump in May. The meeting, if it takes place, will be the first time a sitting U.S. president has met with a North Korean leader. Kim Jong-un is also slated to meet with his South Korean counterpart, President Moon Jae-in, in a face-to-face gathering at the so-called truce village in the Demilitarized Zone on April 27.
