Trump's DOJ Pursues Grand Jury Probe Involving John Brennan and Mar-a-Lago

Sep 17, 2026
Trump's DOJ Pursues Grand Jury Probe Involving John Brennan and Mar-a-Lago

The Justice Department, led by President Trump, is reportedly engaged in a significant grand jury investigation that prosecutors have described as a sweeping conspiracy inquiry related to Mar-a-Lago and other matters. Former CIA Director John Brennan has been named as a subject of this federal investigation, according to documents obtained by RadarOnline.com.

Brennan's attorneys have indicated that prosecutors recently revealed the existence of several ongoing grand jury investigations during discussions about a subpoena for Brennan's testimony. The filing from Brennan's legal team claims that the investigation is extensive, encompassing issues at Mar-a-Lago and potentially beyond.

In a declaration submitted on September 14, Brennan's attorney Kenneth Wainstein stated that he and his co-counsel participated in a conference call with prosecutor Kurt Olsen and other members of the prosecution team. During this call, Olsen reportedly mentioned that there are multiple viable grand jury investigations in progress, including a significant probe based in Fort Pierce, Florida.

The attorneys for Brennan assert that prosecutors characterized the investigation as a more wide-ranging conspiracy. They noted that while Brennan is a target of a narrower investigation in Washington, D.C., concerning statements he made before Congress, he is considered a subject in the broader Fort Pierce investigation.

New Developments in Brennan's Legal Situation

Prosecutors have also informed Brennan's legal team that the narrower investigation remains active and that the conduct being examined could potentially be integrated into the larger case as overt acts. This development follows a subpoena requiring Brennan to testify in Fort Pierce on October 15, which was accepted by his attorneys on September 10.

The subpoena was signed by Joseph diGenova, who was serving as a counselor to the Attorney General at the time. Following the issuance of the subpoena, diGenova resigned from his position, raising further questions about the investigation's direction.

Filed & Cleared

Brennan's lawsuit against Trump and other officials alleges that there is an unlawful government campaign targeting him. This lawsuit names several senior Trump administration officials, including FBI Director Kash Patel, and seeks to block what Brennan describes as an unlawful campaign against him.

As the investigation unfolds, it remains to be seen how the various elements will intersect and what implications they may have for those involved, including Brennan and Trump. The legal landscape surrounding this case is complex, and the outcomes could have significant ramifications for all parties involved.
