COLUMBIA, Mo. (AP) — Missouri Sen. Claire McCaskill is asking students and university officials across the state for help improving national legislation aimed at curbing sexual violence at colleges.

McCaskill on Tuesday continued her statewide tour at the University of Missouri-Columbia, where student advocates and survivors of sexual assault told her about challenges that sometimes prevent victims from reporting.

The U.S. Department of Education reports 76 colleges and universities are under investigation for possible violations of Title IX. The federal anti-discrimination law prohibits sexual assault, stalking and dating violence.

McCaskill’s Campus Accountability and Safety Act would impose new policy guidelines and penalties of up to $150,000 for universities’ noncompliance.
