The NCAA has sent a letter of inquiry to Michigan State University and formally opens an investigation into how the school handled the Larry Nassar situation, according to a report from the New York Times.

Nassar has admitted to sexually assaulting athletes while being employed by Michigan State and USA Gymnastics.

“The N.C.A.A. has requested information from Michigan State about any potential rules violations,” said Donald M. Remy, the association’s chief legal officer, on Tuesday.

NCAA bylaws state “(i)t is the responsibility of each member institution to protect the health of and provide a safe environment for each of its participating student-athletes.”

Nassar has already been sentenced to 60 years in prison on federal charges related to child pornography. He’ll been sentenced this week on seven sexual assault charges.

His hearing will resume Wednesday morning.
