The top federal prosecutor in Manhattan has been recused from Luigi Mangione’s case.

“The Government also writes to inform the Court that United States Attorney for the Southern District of New York, Jay Clayton, is recused from this matter,” attorneys from the U.S. Attorney’s Office for the Southern District of New York said in a letter to Judge Margaret Garnett on Wednesday.

Mangione, 26, is facing federal and state charges in the fatal shooting of UnitedHealthcare CEO Brian Thompson outside a New York City hotel in December.

He pleaded not guilty to a federal murder charge last Friday. Federal prosecutors have declared their intent to seek the death penalty. Mangione pleaded not guilty to state murder and terrorism charges in December.

The letter did not explain why Clayton recused from the case, but said that Perry Carbone, the district’s criminal division chief, will serve as the attorney for the United States in the case.

“Mr. Carbone has conveyed the same to the Office of the Deputy Attorney General, which confirmed that it will in turn notify the Attorney General,” the letter said.

President Donald Trump announced in April that Clayton, a former chairman of the Securities and Exchange Commission, would serve as interim U.S. attorney for Southern District of New York while the administration pursues Senate confirmation for him to serve in the role full-time.

Wednesday’s letter also amended an earlier letter to Garnett that described the handling of a recorded jail call between Mangione and his attorney, Karen Friedman Agnifilo.

The earlier letter has said that a paralegal at the New York County District Attorney’s Office (DANY) had “immediately stopped listening” to the call after recognizing it as an attorney call.

“In fact, the paralegal listened to the entire call, then subsequently informed DANY prosecutors about the identities of the people with whom the defendant spoke,” Wednesday’s letter said.

“DANY thereafter handled the matter as described in our previous letter. Moreover, DANY notified defense counsel of these facts in an email, dated April 22, 2025, thus, counsel was aware of this information prior to arraignment.”

Mangione is next due in federal court on December 5. His next appearance in the state case is set for June 26.

No trial date has been set in either case, but his defense team have said they want the federal case to take precedent because it involves the death penalty.
