WASHINGTON (AP) — President Barack Obama is unveiling new public service announcements against campus sexual assault in a campaign being supported by the NCAA and several media companies with reach among college students.

The White House says athletes will appear in the campaign called "It's On Us" that Obama and Vice President Joe Biden plan to reveal Friday at a White House event. With an estimated one in five college women assaulted, the message is particularly targeted at men.

The NCAA plans to promote anti-assault messages on screens at their championship events. Video game maker Electronic Arts will encourage fans to sign up to pledge to support the campaign through its online platforms. And media giant Viacom will promote the messages on websites, including for music channels MTV, VH1, BET and CMT.
