Oprah Winfrey takes a swipe at JD Vance during surprise Democratic convention speech – video

Oprah Winfrey has made an unscheduled appearance at the Democratic convention, strolling on stage to deafening cheers. The media mogul's message was one of inclusion and unity and notably included a swipe at Donald Trump's running mate, JD Vance, who has criticised women who don't have children. Oprah told the crowd: When a house is on fire, we don't ask about the homeowner's race or religion ... We just try to do the best we can to save them,' adding, 'and if the place happens to belong to a childless cat lady, well, we try to get that cat out, too'
