The Vatican's envoy to the United Nations is strongly hinting at a visit by Pope Francis to New York next year to address world leaders at the U.N. General Assembly, saying that "if he comes to Philadelphia, he will come to New York."

The pope in August confirmed that he wants to visit the United States in 2015 and that he'd like to go to Philadelphia for a family rally. He added that he's also been invited by President Barack Obama and Congress and by the U.N. secretary-general.

Archbishop Bernardito Auza, the permanent observer of the Holy See, told The Associated Press on Thursday that likely only the pope himself will make an official announcement, but next year's 70th anniversary of the United Nations would be "the ideal time."
