President Barack Obama, Vice President Joe Biden and various celebrities have lent their voices to a new campaign aimed at stopping sexual assault on college campuses, launched with a video promoting the It’s On Us official website.

“It’s on us to stop sexual assault,” Kerry Washington, Jon Hamm and others say into the camera. “To get in the way before it happens. To get a friend home safe.”

More pointedly, Joel McHale adds, “To not blame the victim.”

Obama revealed the campaign in a Friday press conference.

He said, “From sports leagues to pop culture to politics, our society does not sufficiently value women. We still don’t condemn sexual assault as loudly as we should.”

Obama also conceded that recent headlines involving NFL players and domestic abuse scandals partly explain the timing of the campaign’s launch.

“We’ve been working on campus sexual assault for several years, but the issue of violence against women is now in the news every day,” he said. “We’re getting a better picture of what domestic violence is all about. People are talking about it. Victims are realizing they’re not alone.”
