Michigan interim president Domenico Grasso sent a letter to the school's students and faculty on Thursday, Dec. 11 regarding the investigation into former football coach Sherrone Moore, which remains ongoing.

It's the first comments from the university since it announced Moore's firing Wednesday, Dec. 10. It does not mention Moore's detainment and arrest that occurred later in the day.

Moore was fired after a university investigation found "credible evidence" he "engaged in an inappropriate relationship with a staff member." In the letter, Grasso said Moore's employment was terminated immediately when the findings of the investigation were presented on Dec. 10.

"There is absolutely no tolerance for this conduct at the University of Michigan. None," Grasso wrote. "I have been in close communication with the Board of Regents and we are united in committing to doing what is right.

"This breach of trust by Coach Moore is painful for many in our community, first and foremost, the individuals directly involved in this situation," he added.
