Today at noon (Eastern time), a group of U.S. bishops, led by Boston's Cardinal Sean O'Malley, will say Mass at the border wall between Mexico and the United States in Nogales, Arizona. "Following the example given by Pope Francis at the Italian island of Lampedusa, where where the Holy Father remembered migrants from Africa who have died trying to reach the island and Europe, the bishops will call attention to the humanitarian consequences of the broken U.S. immigration system."

You can watch a livestream of the Mass, and learn more about the Justice for Immigrants effort, here. It will be followed by a press conference. [UPDATE: Watch the whole thing below.]

Why Nogales? Read Ananda Rose Robinson's 2009 Commonweal article "Borderline: Stranded in Nogales" for a look at what conditions are like there for immigrants, and those who help them.
