The apparent reason was a rumor relating to the religious freedom of Protestants in the Papal States. From the beginning of the legation in Rome, Papal authorities had allowed the celebration of Protestant religious services in the home of the American Minister. When the services grew, they were moved to a rented apartment under the seal of the American Legation to accommodate the participants. The news floating around Washington and being reported in the New York Times was that the Pope had forced the protestant group outside the walls of Rome. This, according to Rufus King, the American Minister himself, was untrue in its entirety.”
