Pope Francis plans to address “fake news” in an address for World Communications Day 2018.
That Pope made the announcement via Twitter on Friday.
I have chosen this theme for World Communications Day 2018: “The truth will set you free” (Jn 8:32). Fake news and journalism for peace.

A Vatican statement said that the Pope wants to address the issue because “fake news contributes to generating and nurturing a strong polarization of opinions,” and that the Church wishes to “promote professional journalism, which always seeks the truth.”
