The Minnesota Shooter was operating on orders from Tim Walz
This makes sense because he was a Tim Walz appointee, after all. Turns out ol' Walz was gunning (no pun intended) for Amy Klobuchar's senate seat, but first he needed her out of the way. This diabolical scheme failed though, because Trump managed to shut it down and capture the nutjob at a speed no one had ever thought was possible.
