Shortly after arriving in South Korea following the visit, Pompeo posted a photo of himself walking along with Kim on Twitter, saying: “Had a good trip to #Pyongyang to meet with Chairman Kim. We continue to make progress on agreements made at Singapore Summit. Thanks for hosting me and my team @StateDept.”
