#ItsOnUs: Watch Obama And Brooke Axtell Deliver A Haunting Message About Domestic Abuse

It's on us -- all of us -- to end abuse and sexual violence.

The 2015 Grammy Awards contained their fair amount of lighthearted fare, but when President Obama appeared during a commercial break to urge artists and fans to take the pledge to end sexual assault and domestic violence via the It's On Us campaign, the show took on a far more somber -- yet necessary -- tone.

"Right now, nearly one in five women in America has been a victim of rape or attempted rape," Obama said. "More than one in four women has experienced some form of domestic violence. It's not okay, and it has to stop. Artists have a unique power to change minds and attitudes, and get us thinking and talking about what matters. All of us, in our own lives, have the power to set an example."

Then, moments before Katy Perry took the stage for her haunting rendition of "By the Grace of God" -- a ballad about the toll of an unhealthy relationship -- Texas-based domestic abuse survivor Brooke Axtell performed a powerful written-word piece about her experience.

"Authentic love does not devalue a human being," Axtell said. "If you’re in a relationship with someone who does not honor and respect you, I want you to know you are worthy of love. Please reach out for help; your voice will save you."
