So in summary:
Bernie finds out there's a conference happening in the Vatican to discuss one of Pope John Paul II's encyclicals. Because the encyclical is about economic justice, Bernie mistakenly thinks he has something to contribute so he badgers the people running the conference, "showing great disrespect" according to them, until they agree to shorten a coffee break to give him time for a ten minute speech. He rudely skips most of the conference but shows up just in time for his speech, refuses to shake the organizer's hand, and reads off a set of prepared remarks that are basically just his stump speech (he only really talks about the American economy) with a couple references to "the moral economy" and a couple quotes from the encyclical dropped in obviously after the fact. At 4 AM that night, as Pope Francis is leaving for his red-eye flight to Greece, Bernie runs up to him in the middle of an open foyer and gets his little handshake. Bernie's people go out in the media and say he had a private five minute meeting with the pope where they discussed very important things. As usual, Bernie lets other people lie for him but eggs them on by saying he "met with the pope" which is technically true. The pope, clearly irritated that Bernie used him as a political prop, accuses Bernie of basically stalking him in the foyer and says his supporters need to get their heads checked.
Just another day in this ludicrous zombie campaign.
Yes. Reuters put out some video of Papa Francisco talking on the plane about this and he was a displeased pontiff until he mentioned that anyone trying to use me for political purposes needs to see a psychiatrist
