BUFFALO, N.Y. (AP) — A high-ranking U.S. cardinal in Boston says he is concerned about a bishop's handling of alleged clergy abuse in the Roman Catholic Diocese of Buffalo and wants the Vatican to step in.

A spokesman for the Boston archdiocese tells WKBW-TV in Buffalo that Cardinal Sean O'Malley reviewed reports on Bishop Richard Malone, and he will send the documents to the Most Rev. Christophe Pierre, Apostolic Nuncio to the U.S.

Malone is facing calls to resign after an investigation found he allowed multiple priests accused of misconduct to return to the ministry.

He previously acknowledged "past inadequacies" in his handling of complaints, but he says he will not resign.

Malone did not respond to a request for comment on O'Malley's statements.
