Zaila Avant-garde made history Thursday as the first African American student to win the Scripps National Spelling Bee. The word she spelled correctly to win was "Murraya," which is a genus of tropical Asiatic and Australian trees. Her victory during the final round also means she is the first Black champion since Jody-Anne Maxwell in 1998. Lisa Desjardins reports on her life and accomplishments.
