While it might embarrass the prosecution, I still don't see how that is connected to the prosecution/persecution. She may and likely drop out but the case will continue without her.
Bigger picture her career is toast, so is his. I sure hope they saved some of that money for the future.
I just explained it. She has abused her prosecutorial discretion to further a corrupt scheme-her own. Presumptively all of her decisions, not just her choice in boyfriends, but her choices in whether not to pursue prosecution are driven by the desire to continue her corruption. Therefore her decisions regarding the prosecution are inherently unreasonable. It is a fundamental principal that exercise of discretion must be reasonable.
I can send you a blindingly long set of legal citiations, but since you don't get the point it is likely of no avail. And no I am not an attorney offering legal advice.
When public prosecutors have any financial interest or motive, actual or potential, in filing a case, the entire case is TAINTED.
The financial interest or motive could be the enrichment of themselves, a spouse, child, other relative, close personal friend, etc. If things did not work this way, prosecutors could indict people and hire “outside attorneys”, as a way to steer public funds to cronies and intimates, whether or not kickbacks were involved.
If Fani Willis was in a personal/romantic relationship with Wade BEFORE selecting him to receive $650,000 (and counting) in legal fees, SHE benefits by enriching her own boyfriend. That is all the proof that is needed to throw her off the case and dismiss it. That Wade paid for her airplane ticket or cruise, etc., is not essential (but it does establish that he was spending money on her).
Once Willis is out of office, theoretically other Georgia DAs unconnected to her could obtain indictments from a new Grand Jury and start over. They would do so under a major cloud, and it would be most unlikely anyone else would step up for career suicide.
