Jason Reding Quiñones, the top federal prosecutor in South Florida, resigned Friday from the Department of Justice. Quiñones had been tapped to oversee a probe into an alleged "grand conspiracy" involving former Obama administration officials who purportedly promoted claims of collusion between Donald Trump's 2016 presidential campaign and the Russian government.

Attorney General Todd Blanche announced Quiñones' resignation on X, formerly Twitter. "We are grateful for Jason’s leadership in combatting violent crime, drug trafficking, sex trafficking, and transnational crime, including the indictment of [former Cuban leader] Raúl Castro," Blanche stated. "Jason has served the Department multiple times over his distinguished career, and we thank him for his service to this country."

The "grand conspiracy" investigation, initiated in August 2025, had led to subpoenas being issued to former CIA Director John Brennan, former Director of National Intelligence James Clapper, and former FBI Director James Comey.

Sources familiar with the probe indicated that its momentum had slowed in recent months. Joe diGenova, the former DC US Attorney who had been leading the investigation, resigned on September 10. He told The Post that "If you want indictments where there’s no evidence, you have an ethical problem."
