Former CIA Director John Brennan Subpoenaed Over Russiagate Conspiracy Against Trump

Former CIA Director John Brennan must testify under oath about his role in a grand conspiracy to frame President Donald Trump as a Russian puppet, according to a new legal filing.

Brennan will be compelled by a subpoena to testify on Oct. 15, 2026, before a federal grand jury sitting in Fort Pierce in Southern Florida, the legal filing shows..

The filing reveals the Justice Department (DOJ) is pursuing two probes, including a far-reaching conspiracy investigation to include “issues at Mar-a-Lago and beyond,” an apparent reference to the 2022 FBI raid of Mar-a-Lago over classified records, and another narrower one related to Brennan’s sworn statements before Congress.

Brennan’s attorney Ken Wainstein revealed the subpoena in a filing in Brennan’s case against the Department of Justice. Brennan has accused Trump’s Justice Department of violating his constitutional rights in pursuit of “phantom criminal conduct.”

Reached through his law firm, Wainstein declined to comment.

The subpoena was signed by former Counselor to the Attorney General Joseph E. diGenova on Sept. 9, 2026. diGenova abruptly resigned as top prosecutor on the Russiagate conspiracy case the next day, on Sept. 10.

The legal filing by Brennan’s attorney includes diGenova’s protestation to the New York Post that “if you want indictments where there’s no evidence, you have an ethical problem.”

It also includes further clarifying remarks he made to the Associate Press indicating that there is indeed evidence of criminal behavior, but that there was a dispute about pacing: “There’s plenty of evidence in all of these cases to prove the theories of prosecution. It just takes time to get there, and some people want to get there a little faster than others — and you can’t do that.”

diGenova first took the reins of the case in April 2026 and was pursuing broad charges, per several reports. Anonymous officials accused him of falling down “rabbit holes.”
