Launching a new wave of celebrity support, the “It’s On Us” campaign just unveiled a brand new PSA for all to see.

The latest clip features Jon Hamm, Samuel L Jackson, Rose Byrne, Kerry Washington, Vice President Joe Biden and President Barack Obama all urging Americans to stand up against sexual assault.

Hamm begins, “It’s on us to stop sexual assault.” “To get in the way before it happens,” adds Ms. Washington.

Also included is “Nashville” star Connie Britton as well as Roots drummer Questlove and “Community” hunk Joel McHale. Check out the video and head over to ItsOnUs.org to sign the petition.
