President Trump has scrapped a surprise visit to the Korean demilitarized zone due to poor weather.

Marine One flew most of the way from Seoul to the DMZ before turning back due to poor weather conditions. Weather reports from near the DMZ showed misting conditions and visibility below one mile.

The White House said Mr. Trump is disappointed the surprise trip to the DMZ was thwarted. Press Secretary Sarah Huckabee Sanders told reporters, "I think he's pretty frustrated" that he had to change his plans.

The White House said Mr. Trump's trip to the DMZ had been planned well before he left for Asia, but it was kept secret due to security concerns.

Sanders convened pool reporters in a hotel meeting room and flashed a piece of paper with the letters, "DMZ," CBS News Radio's Steven Portnoy reports.

"This is where we're going," Sanders said, refusing to use the three letters out loud. She said those were the instructions she was given.

Mr. Trump departed the Grand Hyatt at 7:09 a.m. local time, accompanied by a small coterie of aides, including Secretary of State Rex Tillerson, National Security Adviser H.R. McMaster, chief of staff John Kelly, deputy chief of staff Joe Hagin, speechwriter Stephen Miller and Sanders.

The bad weather call was made as they approached the DMZ. Not quite two hours after they departed Seoul, the decision was made to abort the trip.
