A senior administration official told reporters Tuesday that President Trump will not visit the demilitarized zone on the North Korean border on his upcoming trip to Asia. The official said there isn't enough time, and that they had to choose between going to the DMZ or Camp Humphreys, and the camp prevailed.

Key quote: "There's been a minority of American presidents who have visited the DMZ since the Korean War, less than half," the official said. "[Defense Secretary James] Mattis was just there last week, we've had [Vice President Mike] Pence there... and [Secretary of State Rex] Tillerson... it's become a little bit of a cliché really."
