On September 10, prosecutors presented former CIA Director John Brennan with a subpoena to appear on October 15 before a grand jury in Fort Pierce, Florida, the courthouse of Trump-appointed Judge Aileen Cannon. The lead prosecutor, Joe diGenova, resigned the same day amid reported White House and DOJ frustration over the pace of the probe. Brennan's lawyer called it an attempt to 'frame somebody for a crime that is complete fiction.' Former FBI personnel who worked on the Mar-a-Lago investigation have also been subpoenaed. No one has been charged.","summary":"The Justice Department is using a Florida grand jury to investigate the officials who once investigated Trump, on a theory that the Russia inquiry and the classified-documents case were themselves a criminal conspiracy against him. It subpoenaed former CIA Director John Brennan and former FBI personnel who worked on the Mar-a-Lago investigation. The lead prosecutor quit after reported pressure over the pace of the probe. No charges have been filed, and the targets deny wrongdoing.","category":"rule-of-law","severity":"severe","ongoing":true,"sources":[{"url":"https://www.clickorlando.com/news/politics/2026/09/14/ex-cia-director-john-brennan-issued-subpoena-in-trump-grand-conspiracy-investigation-lawyer-says/","title":"Ex-CIA Director John Brennan issued subpoena in Trump 'grand conspiracy' investigation, lawyer says","publisher":"Associated Press (via WKMG ClickOrlando)"},{"url":"https://www.nprillinois.org/2026-09-15/ex-cia-chief-issued-subpoena-in-trump-grand-conspiracy-investigation-lawyer-says","title":"Ex-CIA chief issued subpoena in Trump 'grand conspiracy' investigation, lawyer says","publisher":"NPR (via NPR Illinois)"},{"url":"https://cbs12.com/news/local/fbi-employees-seek-clarity-on-subpoenas-in-florida-grand-conspiracy-probe-president-trump-investigation-mar-a-lago-florida-news","title":"FBI employees seek clarity on subpoenas in Florida 'grand conspiracy' probe","publisher":"CBS12"}],"draft":false,"status":"published","tags":["DOJ weaponization","grand conspiracy","John Brennan","retaliatory prosecution","Aileen Cannon","Russia investigation","Mar-a-Lago","grand jury"],"relatedEntries":["doj-weaponization-political-prosecutions","doj-comey-indictment-2026","trump-mar-a-lago-classified-documents-indictment","security-clearance-political-retaliation"],"timeline":[{"date":"2026-09-10","title":"Lead prosecutor resigns","summary":"Joe diGenova, the prosecutor leading the 'grand conspiracy' investigation, resigns abruptly amid reported frustration from DOJ and the White House over the pace of the probe."},{"date":"2026-09-10","title":"Brennan subpoenaed","summary":"Prosecutors present John Brennan with a subpoena to testify on October 15 before a Fort Pierce, Florida grand jury."},{"date":"2026-09-14","title":"Subpoena made public","summary":"Brennan's lawyer confirms the subpoena, calling the case an attempt to 'frame somebody for a crime that is complete fiction.'"},{"date":"2026-09-24","title":"FBI Mar-a-Lago investigators seek guidance from Cannon","summary":"Lawyers for subpoenaed current and former FBI personnel who worked on the Mar-a-Lago investigation ask Judge Cannon whether her secrecy order permits them to testify."}],"location":{"name":"Fort Pierce, Florida","lat":27.4467,"lng":-80.3256},"custom":{"era":"second-term","posture":"reported","warCrimeClassification":"enabling","internationalLaw":[{"statute":"International Covenant on Civil and Political Rights","article":"Article 14","provision":"Right to a fair hearing before an independent and impartial tribunal; prosecution must not be used as an instrument of political retaliation"},{"statute":"UN Guidelines on the Role of Prosecutors","article":"Guidelines 12-13","provision":"Prosecutors shall perform their duties impartially and avoid political discrimination"}],"iccRelevance":false,"victims":"John Brennan; former FBI and intelligence personnel who worked on the Russia and Mar-a-Lago investigations","perpetrators":"U.S. Department of Justice; Joe diGenova (lead prosecutor until September 10, 2026); Kurt Olsen","structuredPerpetrators":[{"name":"Joe diGenova","role":"Lead prosecutor of the 'grand conspiracy' investigation (resigned September 10, 2026)","institution":"U.S. Department of Justice"},{"name":"Kurt Olsen","role":"Member of the investigative team","institution":"U.S. Department of Justice"}],"keyPoints":["AP: the probe examines a 'loosely defined theory' that officials who investigated Trump over the last decade conspired to deprive him of his civil rights.","Brennan was presented on September 10 with a subpoena to appear on October 15 before a grand jury in Fort Pierce, the courthouse of Judge Aileen Cannon, who dismissed the classified-documents case against Trump in 2024.","Joe diGenova, who led the probe, resigned on September 10, the day the subpoena was delivered, amid reported frustration from the Justice Department and White House over its pace and management.
