It all comes down to what "news" sources you believe. I don't think anyone would disagree that the shooter here is mentally ill. If you want to believe Walz was involved so be it. I've not seen any credible evidence of that.

Trump controls the FBI via Kash Patel. If there was any way possible to implicate Walz here the FBI could do it.
