After revelations of Fani T. Willis’s romance with a subordinate sent the Georgia criminal case against Donald J. Trump down a two-month detour worthy of a soap opera, a judge’s ruling on Friday resolved a major cliffhanger. Ms. Willis could continue prosecuting the case, so long as her ex-boyfriend withdrew from it.
But the resignation hours later of the former boyfriend, Nathan J. Wade, whom Ms. Willis hired as a special prosector, only settled so much. A fresh and complicated array of problems lies ahead for Ms. Willis, and for one of the most significant state criminal cases in American history.
“Her troubles are far from over,” Clark D. Cunningham, a law professor and ethics specialist at Georgia State University, said in an email on Friday.
The defense effort to disqualify Ms. Willis began in early January, upending the case and making it unlikely to reach trial before the November rematch between Mr. Trump and President Biden. Any attempts to appeal Friday’s ruling by Judge Scott McAfee of Fulton County Superior Court could delay matters even further.
Republicans have smelled blood. The G.O.P. lawmakers who dominate Georgia politics have created new ways to investigate Ms. Willis, which could potentially lead to her removal from office. And last week, a young lawyer named Courtney Kramer, a former intern in the Trump White House, announced that she would run against Ms. Willis in this year’s race for district attorney.
Ms. Kramer’s campaign, while unlikely to succeed in heavily Democratic Fulton County, could amplify criticism of Ms. Willis and the case, which charges Mr. Trump and some of his allies with conspiring to overturn his 2020 election loss in Georgia.
