Anti-bullying summit held in Washington, DC.
Anti-bullying advocates are launching a new campaign to prevent both face to face and online bullying, and the White House is behind the effort.
They're urging victims, as well as those who witness bullying, to take a stand.
"So many people observe bullying and they just look the other way. You don't have to
look the other way, you could actually do something," says White House advisor Valerie Jarrett.
The summit attracted bullying victims like 17-year-old Steven Wayman of Utah.
"I'd get punched, kicked, black eyes, bruises and I'd lie to my mom and say it was nothing, or I fell off slides, I just fell down," he says.
Another bullying victim was superstar Lady Gaga, whose mother described relentless bullying she suffered as a teenager.
"Everything from her locker being defaced at school, she was actually put in a trash can at one point, Cynthia Germanotta recalled.
Germanotta helps with her daughter's own anti-bullying foundation.
"There's some pretty empirical evidence that shows that bystanders can do something to help stop and prevent bullying," she noted.
Germanotta's involvement is what experts say other parents should do.
They say that means even though your child may not be a victim, convince them to tell you of others who are.
