I commented about this in your issue dated 4/19/17.  I cannot believe the Vatican would allow the pope to meet with Donald Trump.  He was fraudulently elected and espouses attitudes and governmental policies that are not in keeping with tenets of Christianity much less Roman Catholicism.  What would they have to say to each other?  If the pope thinks he can influence Mr. Trump, he's mistaken.  Trump is looking for a photo op that implies that Pope Francis will kow-tow to an American president's bigoted and authoritarian agenda.  He seeks reapproachment with the pope, not!  The pope should make himself unavailable.  Such a meeting will sow further discord in the American church.  Is this the outcome aspired to by the Vatican?
