Pope Francis near the U.S.-Mexican border fence Wednesday, able to look into the United States and see people lined up for his blessing. He decried the suffering of immigrants there and in other places, and said politicians who demonize them and build fences against them are not Christians. At a press conference later aboard his plane, he brushed aside criticism that he’s too political, quoting Aristotle that all humans are political animals. (Gregorio Borgia/Associated Press)
