This is Archbishop Chaput we're talking about here. He's kept a recently convicted sex offender priest on the Archdiocese payroll. Why should he excommunicate a Catholic politician?
Whipkey was placed on administrative leave by the Archdiocese of Denver after his arrest.
Chaput believes in due process for the accused and you are not privy to what additional action is being taken in Rome to dismiss Whipkey from the clerical state, are you?
