Texts obtained by The New York Times reveal that Terrence Bradley, a key witness in the effort to disqualify Fani T. Willis, the district attorney prosecuting former President Donald J. Trump, actively helped expose the romantic relationship between Ms. Willis and Nathan Wade, a lawyer working on the case. Despite Bradley's reluctant testimony in court, the texts show his involvement in providing details about the romance. The judge must now assess Bradley's credibility and the impact of the text messages on the case. The defense has argued that the relationship between the prosecutors constitutes "self-dealing," but Ms. Willis maintains that it did not create a conflict under Georgia law. The case has taken a tumultuous turn due to the focus on the prosecutors' romance, with hearings revealing conflicting testimonies and raising questions about the case's future.
