A clip of Joe Biden comforting the son of a school shooting victim has re-emerged online - and touched thousands of viewers.
The footage shows the former Vice President attending a 2018 memorial service for Chris Hixon, the athletic director at Marjory Stoneman Douglas School in Parkland, Florida.
Hixon was one of 17 people murdered in a shooting spree at the school. He died trying to disarm the gunman.
Biden, in the video, asks who Hixon's family are - and is introduced to his wife.
"God love you," Biden says as he turns to walk away.
But from behind the camera, a distressed voice says "I wanted to..."
And up bounds Hixon's son, Corey, hugging the former VP and saying: "I'm his son."
"How are you?", Biden asks, before planting a kiss on his forehead. "Thank you for hugging me. You OK?"
Corey shakes his head no, before burying it again in Biden's chest.
"It's going to be okay," Biden says. "We're going to be okay. I promise."
In September, the clip was used in an advert by campaign group Fellow Americans.
In the ad, Hixon's wife, Debra said: "I don't have it in me a lot of times to give him that comfort, so it meant a lot for somebody else to give him, to take that time and to care enough about him."
Fighting back tears, she added: "My older son calls him Uncle Joe. He can be that person that can comfort our nation and bring us together."
