My theory is that trump literally sacrificed him for several reasons.

1. Shore up the base who was being lost due to Epstein/bankruptcy by giving a clear enemy (the left, who definitely did this, because they are mean)
2. Cause a massive distraction to the Epstein files
3. Give ample cover to crack down on political enemies with ease
4. Get rid of Charlie Kirk. I mean what a d-bag. No one liked him.
