So we have a person that intentionally files frivolous lawsuits against people to harass and bully them as President, who controls the justice department and is now having the DOJ file frivolous criminal complaints against people to harass and bully them. Not a good thing for a healthy society.

The judge should formally refer the matter for prosecution. Perjury is a felony, and when we fail to prosecute it we just reward the liars that get away with it.

Sound like there will me more criminal indictments tossed.

This is exactly it. Trump is a malignant narcissist and views people and policy only in terms of how it affects him. Mamdani was a useful foil to scare people with while he was running for mayor (“look at the Democrats pushing Socialism!”), but now that he spanked the field, Trump sees the potential to score points by riding his coattails.
