When President Donald Trump tried to visit Korea's demilitarized zone on Wednesday morning, his military escorts weren't the only ones wearing camouflage.

White House press secretary Sarah Sanders didn't bring a jacket and found herself chilled in tarmac winds and temperatures that strained to reach 50 degrees.

'One of our brave soldiers was nice enough to loan me his flight jacket,' Sanders told DailyMail.com, 'because I was freezing.'

The tough-girl Trump spokeswoman put the coat on right over her dress and pearls.

A reporter on the scene said Sanders, arms crossed to conserve heat, 'was shivering' and an Army Ranger lent her his coat.

Insignia on the Army Combat Uniform jacket identified it as belonging to a chief warrant officer named Zizelman.

Marine One was grounded at Yongsan after Trump and a military escort tried to fly to the Korean demilitarized zone but could't land there because of thick fog

The president's helicopter pilot couldn't see the other choppers in the convoy becauseof worsening weather conditions, so the mission was scrubbed

A public affairs official at U.S. Army Garrison Yongsan, where Sanders was on Wednesday morning, identified the soldier.

He is Chief Warrant Officer 2 Bobby Zizelman of the 2nd Combat Aviation Brigade, 2nd Infantry Division.

Trump's unscheduled attempt to visit the Korean DMZ was foiled by dense fog that forced his Marine One helicopter to turn around when he was just 5 minutes from the landing zone.

Military pilots in the airborne convoy couldn't see each other and decided to scrub the mission.

Sanders said the president was disappointed, even as he waited gamely for nearly an hour in his limousine for the weather to clear. Instead, she said ruefully, it got worse

'He's actually pretty frustrated,' Sanders told reporters, admitting that the DMZ visit had been planned 'for a little while,' since before the president's Asia trip began and calling it 'something the president wanted to do.'

'This did not work out as planned,' she told reporters later.

'The fog was not going to clear. It didn’t look like it was going to clear for another hour or so and the president had his speech that he can't be late for, in large part because we have to depart on time as well for China,' she said.

Sanders said Trump was 'frustrated' by the cancellation but had no choice other than cancelling his surprise DMZ visit

South Korean president Moon Jae-in was expected to meet Trump there. But the fog was so thick that even if the leaders had made a joint appearance, they would have been staring into the DMZ's void without seeing anything.

Just last week in a pre-Asia trip briefing, a senior White House official downplayed the idea of Trump visiting the DMZ, saying it had become 'a little bit of a cliche' for commanders-in-chief.

Every president but one since Ronald Reagan has made the trek. George H.W. Bush was the lone standout, but he visited the DMZ while he was vice president.

The White House took unusual steps to make sure news of the unplanned side-trip didn't leak, including a cryptic late-night message to reporters about an extra stop on Trump's itinerary – and Sanders declining to tell them verbally where they were going once they arrived for liftoff.

The DMZ along the 38th parallel is 160 miles long but just 2.5 miles wide, with South Korean and North Korean forces lined up on either side; it sits just 35 miles from Seoul, where Trump spent part of Wednesday before flying to China

Instead, she held up a piece of note paper from the Grand Hyatt hotel – where the president and his senior staff slept Tuesday night – with the letters 'DMZ' on it, saying, 'This is where we're going.'

Sanders instructed journalists not to tell the outside world about the destination until they returned.

She said after the run-in with pea-soup fog to the north of Seoul that White House officials were holding out hope that the weather would clear. Instead, conditions worsened and they called it off.

'There wasn't enough visibility to land,' she explained. 'It would have been really dangerous, and our guys pulled back.'
