From the article:
She then asked the county’s legal counsel – Nate Edwards of the district attorney’s office – to clarify the county’s requirements when honoring requests from groups wishing to deliver the invocation.

Edwards said that satanic invocations are part of a trend.

“The federal law is that you don’t have to open your floor for invocations,” he said. “If you do open your floor for invocations, then federal law is that you have to let everybody have a turn signing up. So I guess you take the good with the bad.”

I’m glad that Nate Edwards left open the definition of “good” and “bad”.
