Nonsense. Neither Gov Kemp nor Pres Trump waived their authoritarian magic wands to dismiss the criminal charges. The regular legal process took its course. Defendant's filed motions before the trial judge who ruled upon them. The ruling was appealed to the court of appeals which issued its order. The matter is currently pending in the supreme court of Georgia.
Similarly, with respect to the statute allowing defendants to recoup their attorneys fees when a prosecutor is removed from the case, this bill was passed by both state houses and signed by the Governor.
I've previously said I'm not a big fan of these ad hoc tariffs. They are not the unmitigated disaster as predicted here but they are preventing (along with interest rates) the economy from taking off.
