US rapper Kanye West's chaotic launch of his unlikely campaign to oust Donald Trump in November's presidential election has sparked anger, concern for his mental health and questions about whether he is seriously running.

Wearing a bullet-proof jacket marked "security," West broke down in tears during a rambling speech in Charleston, South Carolina on Sunday (July 19) that was supposed to kickstart his White House bid.
