U.S. Education Secretary Betsy DeVos was confronted by largely silent protesters holding signs opposing the Trump administration's promotion of for-profit schools and changes to how colleges handle sex assault allegations at a speech at Harvard University on Thursday.

DeVos ignored the protesters, but took questions from audience members on issues, including a White House move to reverse Obama-era guidance on how colleges should handle allegations of sexual assault on campus.

"One sexual assault is one too many, but by the same token, one that is denied due process is one too many," DeVos said. "So we need to be sure that policy is fair to all students."
