MILWAUKEE (AP) -- A group that supports victims of clergy sexual abuse says it will file a fraud lawsuit today against the diocese of Green Bay.

Peter Isely of Milwaukee represents the Survivors Network of those Abused by Priests. He says the suit would give the diocese an opportunity to be transparent and accountable to Catholic faithful and to children who were sexually assaulted by clergy.

In a letter to be given to Archbishop Timothy Dolan this afternoon, Isely calls upon the diocese to argue the lawsuit on its merits, not legal technicalities.

Isely says there are documents showing that the diocese secretly transferred a known pedophile priest numerous times in 30 years, instead of exposing him as a child molester.
