The video in question edited existing footage of the US President with his granddaughter to make it appear as though he was touching her inappropriately.

Because it was not manipulated using artificial intelligence, and depicted Mr Biden behaving in a way he did not, rather than saying something he did not, it did not violate Meta’s manipulated media policy - and was not removed.

“It bans altered videos that show people saying things they do not say, but does not prohibit posts depicting an individual doing something they did not do,” he said.
