Pittsburgh Bishop David Zubik is facing calls for his resignation in the wake of a sweeping state grand jury report on child sex abuse by Roman Catholic priests. SNAP, the Survivors Network of those Abused by Priests, released a statement Wednesday, saying Zubik should step down. It also said Catholics should stop donating to the Diocese of Pittsburgh until he resigns or takes proven steps that protect kids. After the report’s release, Pennsylvania Attorney General Josh Shapiro accused Zubik and Cardinal Donald Wuerl, the former bishop of Pittsburgh, of protecting child predators. Both have denied the accusation.
