Nashville officials are investigating a worship event outside the historic courthouse Sunday that packed together a big, largely unmasked crowd, despite rising new case counts of COVID-19 in Tennessee. The Nashville Health Department says “appropriate penalties” will be pursued against the organizer, saying that person didn’t submit an application to health officials or permit application to any Nashville department.

“We have worked very hard to slow the spread of COVID by taking a measured approach to protect the community,” health department spokesperson Brian Todd said in Monday’s statement. “The Health Department is very concerned by the actions that took place at the event and we are investigating and will pursue appropriate penalties against the organizer.”

Event leader Sean Feucht posted videos of the gathering on social media, calling it a protest. The videos show several hundred people gathering in front of a stage.
