SACRAMENTO, Calif. (AP) — California is on the brink of becoming the first state to define when “yes means yes” while investigating sexual assaults on college campuses.

A bill doing so, SB967, passed the Assembly on a 52-16 vote Monday as states and universities across the U.S. are under pressure to change how they handle rape allegations. It now heads back to the Senate for what is expected to be a final vote on amendments.
