Bishop Robert Barron and Cardinal Timothy Dolan are scheduled to speak at the Trump administration’s daylong prayer celebration this weekend.

The nine-hour "Rededicate America as One Nation Under God" prayer rally highlighted the growing right-wing Christian movement's campaign to dismantle the core U.S. principle of separation of church and state.

The U.S. officials who will speak "are political lieutenants of an administration that has waged war on immigrants, gutted Catholic Charities contracts, and treated the Holy Father as an adversary," said one critic.
