Any update on threat to Oklahoma schools?

Anyone here know some details about the threat to Oklahoma schools from yesterday? The sheriff folks are understandable tight lipped right now. I think some schools closed for a bit, and other have added security. I was looking for details about the threats that were posted online. I think TikTok and Snapchat were listed but I don't see what specifically was said in the threats. And I'm wondering what groups had what complaints. We're a very red state and I'm not surprised that volatile libs would have a beef with our politics but I don't recall a specific school policy...
