President Donald Trump held a rally in Wilkes-Barre, Pennsylvania, on Thursday night and earlier this week in Tampa, Florida.

The events included a lot of the Trump's usual talking points about how well the economy is doing and how much he despises mainstream media outlets like CNN.

But another element — which had mostly been present online — became very public. That was a growing group of attendees who are believers in what’s being called "QAnon."

To explain more about QAnon and related criticism of media outlets and journalists is Margaret Sullivan, media columnist for the Washington Post.
