Miami US Attorney Resigns Amid $0 Charges in Grand Conspiracy Probe

Jason Reding Quiñones resigned as the U.S. attorney for the Southern District of Florida on Friday. He had led the federal office responsible for managing the administration's long-running investigation into alleged plots against President Donald Trump. His departure follows the exit of John Eisenberg, the department's top national security official, who also announced his resignation on Friday.

The probe, often referred to as the grand conspiracy investigation, has struggled to maintain momentum over the past year. In recent weeks, investigators delayed scheduled grand jury testimony for several witnesses. These delays occurred alongside frequent staff changes and a lack of formal charges filed against any high-level targets. Quiñones was confirmed by the Senate last year to lead the office in Miami, which serves as the central hub for this inquiry.

The current wave of departures began earlier in the week. Assistant Attorney General Harmeet Dhillon announced her departure on Thursday. She had led a major reorganization of the Civil Rights Division. Blanche, the Attorney General, confirmed Eisenberg's resignation on Friday. Eisenberg served as the head of the National Security Division starting in June 2025. His division handled cases involving espionage, terrorism, and export control violations.

The investigation has seen several leadership changes since it began. In April, a lead prosecutor on the case involving former CIA Director John Brennan was replaced after questioning the strength of the evidence. Joseph diGenova, a former U.S. attorney for the District of Columbia, then took over the probe. DiGenova resigned in September without filing criminal charges against anyone. The case has since remained without a definitive outcome.

Blanche praised Quiñones for his work in combating violent crime, drug trafficking, and sex trafficking. The Attorney General specifically noted the indictment of Raúl Castro by Quiñones' office in May. Castro, the former Cuban president, faces charges related to the 1996 downing of civilian planes flown by Miami-based exiles. Quiñones stated in a social media post that he leaves with immense pride and gratitude for the opportunity to serve.

Eisenberg oversaw the prosecution of former national security adviser John Bolton. Bolton pleaded guilty this year to allegations of mishandling classified information and is currently awaiting sentencing. Blanche said Eisenberg served with distinction in strengthening the nation's ability to address foreign and domestic threats. The Justice Department did not provide a specific timeline for filling these vacant positions.

The resignations add to a pattern of personnel turnover within the department. The probe into former law enforcement and intelligence officials has continued through various management changes. Quiñones expressed thanks to President Trump and his staff in the Southern District of Florida for their dedication to justice and the rule of law.
