Former friend testifies that Fulton County District Attorney Fani T. Willis and special prosecutor Nathan J. Wade were romantically involved since 2019, before Wade was hired. Testimony suggests relationship persisted until 2022, raising conflict of interest concerns in case against Donald Trump and co-defendants. Defense argues hiring was financially motivated, with Wade earning over $650,000 and allegedly charging vacations to his credit cards. Willis denies impropriety, claiming reimbursement for trips made in cash. Testimony could impact case's trajectory and perceptions of prosecutorial integrity. Fulton County District Attorney, Fani T.
