WATCH: Moment Donald Trump surprises White House tour group
US President Donald Trump paid a surprise visit to a group of school children who were on a tour of the White House, telling the kids to "Work hard".
In the video, Trump pops out from behind a privacy wall and pulls a boy from the tour group.
It was the first public tour of the White House since Mr Trump took over office.
Bizarrely, there was a portrait of his political rival and former First Lady Hillary Clinton at the spot where he emerged.
"Work hard...work hard," he said, before returning to the other side of the wall.
