Bishop Robert Morneau, Auxiliary Bishop Emeritus of Green Bay, has withdrawn from public ministry saying he regrets having failed to report the abuse of a minor, WBAY reported Thursday.

“I failed to report to local authorities an incident of abuse of a minor by a priest in 1979 and, as a result, this priest was able to abuse again several years later,” Bishop Morneau wrote in a letter to Bishop David Ricken of Green Bay, which WBAY says was published in The Compass, the Green Bay diocesan paper.
