Jason Reding Quiñones, the U.S. attorney for the Southern District of Florida who oversaw investigations examining earlier federal probes involving President Donald Trump, resigned from the Justice Department on Friday, Attorney General Todd Blanche announced.
Blanche did not give a reason for Quiñones' resignation, which took effect on November 6.
CNN reported, citing people familiar with the matter, that Quiñones left under pressure from department leadership following concerns about the progress of a wide-ranging investigation into former government officials involved in investigations of Trump and his campaign.
The inquiry has examined whether former intelligence and law-enforcement officials engaged in a conspiracy to violate Trump's rights through investigations dating back to his 2016 presidential campaign.
Reuters and ABC News reported that the effort has so far produced no criminal indictments related to that alleged conspiracy.
Quiñones' departure came alongside the resignation of John Eisenberg, the assistant attorney general leading the Justice Department's National Security Division.
Harmeet Dhillon, who headed the department's Civil Rights Division, resigned on Thursday, bringing the number of senior DOJ departures since Tuesday's midterm elections to three, according to CNN and ABC News.
Blanche said Quiñones had led efforts against violent crime, drug trafficking, sex trafficking and transnational crime, and cited his office's indictment of former Cuban President Raúl Castro.
The departures come after Democrats secured control of both chambers of Congress in the November 3 midterm elections.
The Associated Press reported that Democrats reached the 218-seat threshold needed for a House majority and also regained control of the Senate.
That result gives Democrats congressional committee leadership and expanded authority to conduct oversight of the Trump administration when the new Congress convenes.
Quiñones had served as U.S. attorney since August 13, 2025, according to an official Justice Department profile, after being nominated by Trump and confirmed by the Senate.
His resignation leaves leadership of one of the department's most politically sensitive investigative efforts uncertain as congressional scrutiny of the Justice Department is expected to increase.
