Justice Department officials in Miami and Washington, D.C., are actively preparing to issue several grand jury subpoenas relating to an investigation into former CIA Director John Brennan, Fox News has learned.

U.S. Attorney for the Southern District of Florida Jason Reding Quiñones is supervising the probe, Fox News is told.

Fox News reached out to the Justice Department, but sources there declined to comment. 

Fox News first reported that Brennan and former FBI Director James Comey were under investigation as of early July 2025. Thursday’s development intensifies that investigation. Comey is fighting his case in court with a trial set for January.

Brennan has not been indicted, and it’s unclear if a grand jury would indict him, but evidence will be presented in South Florida.
