Democratic U.S. presidential candidate Joe Biden says the death of George Floyd will "change the world."

The 77-year-old made the remarks in an interview with CBS news, saying Floyd’s death was "one of the great inflection points in American history."

George Floyd died on 25 May after a white police officer knelt on his neck for several minutes as he and his colleagues arrested him.

An onlooker's cell phone recorded the incident showing the 46-year-old black man moaning, "Please, I can't breathe" and "Don't kill me" as the police officer pressed his knee onto Floyd's neck.

After several minutes of the police office pressing his knee on Floyd’s neck, the victim went silent and was later pronounced dead.

The video quickly went viral on social media, sparking widespread protest from Tuesday afternoon, some of which have deteriorated into chaos.

In the two weeks since his death, protests has spilled beyond the U.S. as countries across the world show solidarity with the demonstrators seeking justice for Floyd’s family.

Speaking to CBS, Biden said: "They're an incredible family, his little daughter was there, the one who said 'daddy's going to change the world', and I think her daddy is going to change the world."

"I think what happened here is one of the great inflection points in American history, for real, in terms of civil liberties, civil rights and just treating people with dignity."
