    Pope Francis will celebrate an outdoor Mass when he visits Washington in September.

    The Archdiocese of Washington says the pope will celebrate Mass on Sept. 23 outside of the Basilica of the National Shrine of the Immaculate Conception.

    The archdiocese says details are still pending. The congregation is expected to assemble around the basilica on the university mall.

    The White House has announced that President Barack Obama will meet with Pope Francis on Sept. 23 as well. And House Speaker John Boehner has said the pope will address a joint session of Congress on Sept. 24.
