"Sexual assault is the ultimate abuse of power, and its pernicious presence in our schools is unacceptable," Biden wrote in a Facebook post on Thursday.

"Policies that do not treat this epidemic with the utmost seriousness are an insult to the lives it has damaged and the survivors who have worked so hard to make positive change."

"Students have taken on this fight," Biden continued. "Keep fighting. Tell this administration that we refuse to go backwards."

Biden's comments come after Devos said she intended to rework Title IX guidelines established in 2011, a process she called a "failed system." Although details surrounding the rollback remain unclear, DeVos said they had begun the "extended" process.

Under Title IX, sexual violence on college campuses were categorized as gender discrimination.

The Obama administration significantly expanded the guidelines, a move that was praised by various victim-advocacy groups. The changes meant that federally funded educational institutions would be subject to penalties if they failed to meet Title IX guidelines. Critics of the expansion claimed that the policy lowered the bar for the victim's burden-of-proof and was a significant judicial overreach.

Biden has been a staunch advocate for sexual-assault prevention, launching a campaign and giving several speeches at colleges on the subject.

"We will have succeeded when no woman who is abused ever instinctively asks the question, 'What did I do,'" Biden said at George Mason University in April.
