A tweet from the former US president has become the second most liked in Twitter history, according to Twitter. On Tuesday, it reached 2.5 million likes. His Saturday tweet, which quotes the late South African President Nelson Mandela, followed white supremacist violence in Charlottesville, Virginia. 

"No one is born hating another person because of the color of his skin or his background or his religion," reads the tweet, posted along with a photo of Obama looking up to a window of children of different ethnicities and races.
