Why is Trump standing up for religious teenagers?

Donald Trump is trying to shore up his evangelical support before November's presidential election. Ramping up his Christian outreach, he's been helping teenagers who say they’re being bullied for their religious beliefs at school. These students have organised “prayer lockers” and are running a nationwide “Pray Anyway” campaign. BBC reporter Tara Mckelvey visited one of them in Kentucky to find out how the teenager's struggle went all the way to the White House.Presenter: Matthew Price Producers: Duncan Barber and Seren Jones Mixed by Emma Crowe Editor: Philly Beaumont
