ROME — Pope Francis has confirmed he wants to come to the United States next year and is considering a three-city trip in September: Philadelphia for a family rally, Washington to address Congress and New York to speak at the United Nations.

Francis said there was a proposal to tag Mexico onto the trip so he could visit the Madonna of Guadalupe shrine beloved by Mexican Catholics, “but it’s not sure.”

Francis made the comments Monday while returning to the Vatican from South Korea.

Asked about his 2015 travel plans, he said: “Next year I’d like to go to Philadelphia for the family meeting. I was invited by the president of the United States, by the American parliament and the secretary-general of the United Nations.”

He said “so maybe the three cities together.”
