Iowa professor N. William Hines, chairman of the Presidential Committee on Athletics, an oversight panel, praised Mason for making a definitive statement in response to growing public pressure.
"This hopefully will put some of the uncertainty to rest and we can go back to everyday life here," he said.
Hines said Mason's decision to choose the university's internal auditors to further investigate made sense, given their reputation for professionalism and fairness. But he said he was unsure whether the public would ever receive a full accounting of what happened with Gray's employment.
Iowa Board of Regents President Craig Lang expressed confidence in Mason's response.
"Her deep concern for the safety of students, faculty and staff, and her solid determination to identify answers and address the specific findings of this case will lead the University to the necessary conclusions," he said.
