Media blackout ping
It wasn’t blacked out altogether. NPR had a lengthy radio report (unsurprisingly, in its customary snarky tone). The report, which you can listen to online, had snippets from the event organizer, Reverend Mahoney, as well as some in the crowd.
I don’t watch TV, but others have told me that the event had some coverage on local network-affiliate TV news programs. Certainly we saw big professional cameras set up there and there were quite a few people walking around with monstrous cameras and press credentials dangling on their chests.
But if the national press didn’t cover it adequately, I’d place part of the blame on the event organizers. Here I am, an involved and media-attuned Catholic, and I didn’t hear about the thing until a few days before it took place. So something is wrong with the media contact.
