Tweedy said he did not believe the allegations against Gray and questioned whether they were politically motivated.
Mason told KGAN-TV in an interview Wednesday that she would use the meeting with regents to lay out "a really sound strategy for going forward." She told the station, in her first interview on the case, that school officials were working quickly to learn what happened and would take appropriate actions.
"Believe me, I'm as impatient as everyone else in terms of understanding the full scope of what we're dealing with here and understanding all the facts so that we can make the best decisions possible," she said.
History professor Jeffrey Cox, chair of a university oversight subcommittee on academic achievement in athletics, praised Mason's approach.
"I think President Mason is doing the right thing here by trying to make sure she has all the information," he said. "It would really be a terrible mistake to act prematurely in various ways on this until she knows exactly what happened and when."
In a statement Thursday, Conway, S.C.-based Coastal Carolina confirmed Gray was fired in 1999 after less than a year as its director of retention and advisement because of "unsatisfactory work results." The school's review found no evidence that Gray committed misconduct.
Indiana University also confirmed Thursday that Gray worked as an athletics department advisor from 1999 until 2002. A spokesman said the school was still checking into the circumstances of Gray's departure and work history.
The University of Mississippi said Wednesday that Gray was the athletic department's director of academic support from 1995 until he resigned in 1998.
