WASHINGTON — Joe diGenova, an ally of President Donald Trump, said Thursday that he resigned from his position leading a Justice Department investigation into whether former law enforcement and intelligence officials conspired against the Republican president. His departure came five months after he returned to the department and as new subpoenas demanded testimony before a federal grand jury in Florida, where the investigation has been based. [The Associated Press](https://apnews.com/article/trump-justice-russia-probe-5741c227d76e813c01923df943b8544e) reported the resignation on September 10, 2026.
“I did in fact resign,” diGenova told The Associated Press, calling it an “honor and a privilege” to serve Trump and the Justice Department.
DiGenova declined to comment on the circumstances of his departure. A Justice Department spokesperson did not immediately return a message seeking comment.
The investigation is aimed at trying to establish a conspiracy against Trump involving former government officials who had scrutinized him during the previous decade. Its scope has been loosely defined, but it had recently shown signs of accelerating through the new grand jury subpoenas.
DiGenova, 81, served as the U.S. attorney for the District of Columbia during the Reagan administration. He returned to the Justice Department in April and was given responsibility for the investigation.
Before receiving the assignment, diGenova had asked then-Attorney General Pam Bondi to appoint him to the position. He has openly and repeatedly claimed that Trump was the victim of an intelligence community conspiracy.
