In his first rally for his last-minute presidential campaign, rapper Kanye West ranted against abortion and pornography, argued policy with attendees and at one point broke down in tears.

West, 43, a former supporter of President Donald Trump who has left voters befuddled over whether his campaign is genuine or a publicity stunt to help sell albums or merchandise, delivered rambling remarks during the event at a Charleston, South Carolina, wedding venue and convention center.

In remarks that lasted just over an hour, he denounced abortion, swore, called on random members to speak, appeared to be putting forward policy proposals on the fly, and made comments that left even those in attendance muttering in disbelief.

"Harriet Tubman never actually freed the slaves. She just had the slaves work for other white people," he said at one point when discussing economic inequality.
