Georgia judge unsealed a divorce case involving Atlanta district attorney Fani T. Willis, who is prosecuting former President Donald J. Trump. The case involves allegations of a romantic relationship between Willis and a prosecutor she hired. The unsealing could reveal evidence of the relationship. The accusations have not affected the Trump prosecution, but could complicate it. There are also concerns about county funds and ethics violations related to the hiring of the prosecutor. The judge has delayed Willis's deposition and ordered both parties to appear in court in January.
