Former CIA Director John Brennan has been subpoenaed to testify before a Florida grand jury on October 15, as part of a federal investigation into whether former law enforcement and intelligence officials conspired against former President Donald Trump, according to a court filing by his attorney.
The subpoena, presented to Brennan’s legal team on September 28, directs him to appear before the grand jury in Fort Pierce, Florida. His attorney, Ken Wainstein, confirmed the subpoena in a court document but did not disclose additional details about the investigation’s scope or specific allegations.
Prosecutors informed Wainstein that the probe is examining a criminal conspiracy theory involving officials who investigated Trump over the past decade. The investigation reportedly focuses on whether these officials conspired to deprive Trump of his civil rights, though the legal basis and specific conduct under scrutiny remain undisclosed.
The Justice Department has not publicly commented on the subpoena or the broader investigation. The case is being handled in the Southern District of Florida, where the grand jury is seated.
Brennan, who led the CIA from 2013 to 2017, has been a frequent public critic of Trump’s policies and rhetoric. He has previously testified before Congress regarding Russian election interference in 2016 and other matters related to Trump’s tenure. The investigation’s potential connection to Trump’s 2022 retention of classified documents at Mar-a-Lago has not been confirmed by officials.
Legal experts note that grand jury proceedings are typically confidential, and subpoenas do not imply wrongdoing by the recipient. Brennan’s legal team has not indicated whether he intends to challenge the subpoena or assert any legal defenses.
The investigation adds to ongoing scrutiny of actions taken by federal agencies during and after Trump’s presidency, including the Russia probe and subsequent inquiries into his handling of classified materials.
