The government on Wednesday ordered Michigan State University to make sweeping changes and pay a $4.5 million fine. This comes after determining that it failed to adequately respond to sexual assault complaints against Larry Nassar, a former campus sports doctor who molested elite gymnasts and other female athletes.

Education Secretary Betsy DeVos announced the penalty after the conclusion of two federal investigations. She said Nassar’s actions were “disgusting and unimaginable” and that the university’s response fit the same description.

“Too many people in power knew about the behaviors and the complaints and yet the predators continued on the payroll and abused even more students,” DeVos said in a call with reporters. “This must not happen again, there or anywhere else.”
