Questions swirled Thursday about the origins of Pope Francis’ bombshell comments endorsing same-sex civil unions, with all evidence suggesting he made them in a 2019 interview that was never broadcast in its entirety. The Vatican refused to comment on whether it cut the remarks from its own broadcast or if the Mexican broadcaster that conducted the interview did. And it didn’t respond to questions about why it allowed the comments to be aired now in the documentary “Francesco,” which premiered Wednesday.
