He's trying to find out if Kim Jong Un is really willing to give up his nuclear weapons. "It will happen!" Mr. Trump tweeted Sunday afternoon.
A team led by White House Deputy Chief of Staff Joe Hagin is scheduled to be in Singapore this weekend, meeting with North Korean officials to plan for the June 12 summit.

North Korea defends its nuclear and missile programmes as a deterrent against perceived aggression by the United States, which keeps 28,500 troops in South Korea, a legacy of the 1950-53 Korean war, which ended in a truce, not a peace treaty.
