President Obama taped an anti-gun violence message for the 2016 ESPY Awards show praising Zaevion Dobson, the 15-year-old football player from Knoxville, Tenn., who died in December after he shielded a group of girls from a spray of bullets.

“Zaevion gave his life to save someone else’s. What’s our excuse for not acting?” Obama will say in his message to the sports award show.
