ST. PAUL, Minn. (AP) - The retired Archbishop of St. Paul and Minneapolis, Harry Flynn, has resigned as chairman of the University of St. Thomas Board of Trustees.

In a statement Saturday, the school says the board accepted Flynn's retirement at its regular meeting Thursday. The statement also confirmed the board's vice chairman, the Rev. Kevin McDonough, resigned Oct. 4.

The statement did not give reasons for Flynn's or McDonough's resignations, and university spokesman Doug Hennes declined to comment.

But both men had been under criticism in recent weeks for their handling of clerical sexual abuse cases.

The statement did say St. Thomas has retained outside counsel to lead an independent investigation of "matters related to clergy sexual abuse allegations that impact the university" and has appointed a special committee to oversee the investigation.
