Donald Trump said on Monday he has a good idea of how Kim Jong Un is doing and hopes he is fine. “I can’t tell you exactly. Yes, I do have a very good idea, but I can’t talk about it now.” Trump then suggested the mystery would be solved soon. “I hope he’s fine. I do know how he’s doing relatively speaking. We will see - you’ll probably be hearing in the not too distant future." Kim’s whereabouts and whether he had a heart procedure have been a subject of intense speculation. Daily NK reported Kim was recovering after undergoing a cardiovascular procedure on April 12th. According to Reuters, they have not been able to confirm the report. A special train possibly belonging to Kim was spotted last week at the North Korean resort town of Wonsan.
