Pope Francis presided at his weekly audience with the public at the Vatican, but he said that he’s still unwell and asked an aide to read his remarks for him on Wednesday.

Francis, who will turn 87 on December 17 and had part of one lung removed as a young man, coughed near the end of the hourlong audience in a Vatican auditorium as he made some final comments, then stood up from his chair on the stage to give his blessing.
