Miami US Attorney and National Security Chief Quit Justice Department

Jason Reding Quiñones resigned as the U.S. attorney for the Southern District of Florida on Friday. His departure was announced alongside the exit of John Eisenberg, who served as the head of the Justice Department's National Security Division. Attorney General Todd Blanche confirmed both resignations in a social media post.

Quiñones had led the office tasked with overseeing the investigation into alleged plots against President Donald Trump. Known as the 'grand conspiracy' probe, the case has faced repeated delays and staff changes. In recent weeks, investigators postponed scheduled grand jury testimony from several witnesses. The probe has also seen leadership changes, including the September resignation of Joseph diGenova, a former U.S. attorney who took over the case after a key prosecutor raised doubts about its strength.

Eisenberg, who was sworn in as assistant attorney general in June 2025, managed cases involving espionage, terrorism, and cyber crimes. His tenure included the prosecution of former national security adviser John Bolton. Bolton pleaded guilty this year to mishandling classified information and is now awaiting sentencing.

The resignations follow the departure of Harmeet Dhillon, who left Thursday after leading a restructuring of the Civil Rights Division. Dhillon's exit and the departures on Friday mark a wave of personnel changes at the Justice Department following the midterm elections.

Blanche praised Quiñones for his work on violent crime, drug trafficking, and transnational crime. He specifically cited the May indictment of former Cuban president Raúl Castro. Castro faces charges related to the 1996 downing of civilian planes flown by Miami-based exiles.

Quiñones stated in a post that he is leaving with immense pride in the office's accomplishments. He expressed gratitude to President Trump and the staff of the Southern District of Florida for their commitment to the rule of law. Blanche described Eisenberg as having served with distinction in strengthening the nation's response to foreign and domestic threats.
