President Trump surprised the first White House tour group since he took office, popping out from behind a partition as they admired Hillary Clinton's First Lady portrait.
The group had come to a stop in the Cross Hall of the East Wing when he appeared suddenly, sparking loud applause and cheers from the shocked crowd.
He beckoned children in the group to come forward for a photograph but only one took him up on the offer, 10-year-old Jack Cornish from Birmingham, Alabama.
The pair posed for photographs and shared a tender hug beneath the portrait which Clinton received in 2004, three years after her husband left office.
