Fani T. Willis, the top prosecutor in Fulton County, Ga., is targeting former President Donald J. Trump and a range of his allies in her newly announced investigation into election interference.
Ms. Willis and her office have indicated that the investigation, which she revealed this week, will include Senator Lindsey Graham’s November phone call to Brad Raffensperger, Georgia’s secretary of state, about mail-in ballots; the abrupt removal last month of Byung J. Pak, the U.S. attorney for the Northern District of Georgia, who earned Mr. Trump’s enmity for not advancing his debunked assertions about election fraud; and the false claims that Rudolph W. Giuliani, the president’s personal lawyer, made before state legislative committees.
“An investigation is like an onion,” Ms. Willis told The New York Times in an interview. “You never know. You pull something back, and then you find something else.”
She added, “Anything that is relevant to attempts to interfere with the Georgia election will be subject to review.”
Kevin Bishop, a spokesman for Mr. Graham, said that he had not had any contact with Ms. Willis’s office. Mr. Giuliani did not respond to a request for comment.
Jason Miller, a spokesman for Mr. Trump, has called the Georgia investigation “the Democrats’ latest attempt to score political points.”
The activity of Mr. Trump is central to the Georgia inquiry, particularly his call last month to Mr. Raffensperger, during which Mr. Trump asked him to “find” votes to erase the former president’s loss in the state.
Ms. Willis, whose jurisdiction encompasses much of Atlanta, laid out an array of possible criminal charges in recent letters to state officials and agencies asking them to preserve documents, providing a partial map of the potential exposure of Mr. Trump and his allies.
Mr. Trump’s calls to state officials urging them to subvert the election, for instance, could run afoul of a Georgia statute dealing with criminal solicitation to commit election fraud, one of the charges outlined in the letters. If that charge is prosecuted as a felony, it is punishable by at least a year in prison.
Ms. Willis, 49, is a veteran prosecutor who has carved out a centrist record. She said in the interview that her decision to proceed with the investigation “is really not a choice — to me, it’s an obligation.”
“Each D.A. in the country has a certain jurisdiction that they’re responsible for,” she added. “If an alleged crime happens within their jurisdiction, I think they have a duty to investigate it.”
