Serena Williams isn't just the best tennis player in the world, she's also one of the most charitable

Serena Williams' charity, the Serena Williams Foundation, has announced a grant to the Caliber Foundation, which helps victims, families and communities damaged by gun violence in the US.
"When someone is killed or wounded through acts of senseless violence, there are many victims," Williams said at the launch event.
"Aside from the person whose life was lost, there are the children, families and communities left struggling for answers or simply left with a hole in their heart."
