Amara and Leela, two of Vice President Kamala Harris' nieces, took the main stage Thursday at the Democratic National Convention for a lesson on how to pronounce their aunt's name. "First you say comma, like comma in a sentence," Amara said. "Then you say, 'La,' like lalalala," Leela finished. Day 4 of the DNC is focused on the future as Kamala Harris formally accepts her party’s nomination for president. Her nieces were introduced and accompanied on stage by actress Kerry Washington. Harris’ speech is her first official chance to offer her vision for the country to voters. Minnesota Gov. Tim Walz formally accepted the vice presidential nomination the day before.
