Cardinal Timothy Dolan is heading to the Republican National Convention.
New York's Archbishop was invited to give a benediction during next week's event.
Presumptive nominee Mitt Romney broke the news during an appearance on the Catholic TV network EWTN.
Traditionally, the local bishop would give the prayer but in this case, the GOP asked Dolan if he would deliver it.
Cardinal Dolan will take the stage on the same night Romney will accept the party's nomination.
A spokesman for Dolan said the Cardinal told the RNC he would go to the Democratic National Convention if invited.
