For nine years John Brennan has been the man who explained the Trump-Russia investigation to the country. This week the Justice Department told him, in writing, that he is now a target of one.
Story Snapshot
- On September 14, Brennan’s attorney Ken Wainstein disclosed in a court filing that prosecutors served a grand jury subpoena on the former CIA director the previous Thursday, September 10.
- Brennan is ordered to appear October 15 before a federal grand jury in Fort Pierce, Florida.
- Prosecutors have labeled him a “target” of a false-statements investigation and a “subject” of a broader probe into whether officials “conspired to deprive Trump of his civil rights.”
- The man who ran the Florida probe for five months, Joseph diGenova, resigned last week. The subpoena went out anyway.
The Word That Changed: “Subject” Became “Target”
Federal prosecutors use two labels for people they question, and the difference is everything. A “subject” is someone whose conduct falls inside the investigation. A “target” is someone prosecutors believe they have substantial evidence against. According to the filing reported September 14, Brennan is a target of the inquiry into whether he lied to Congress in 2023 about the intelligence community’s conclusion that Russia sought to help Trump in 2016, and a subject of the wider conspiracy case. That is the sharpest language the government has used about him since the probe began.
The subpoena requires testimony, not a plea. It is not an indictment. But a target letter paired with a grand jury date is the step that usually comes right before prosecutors decide whether to charge. For a man who spent years on cable television describing other people’s legal exposure, the exposure is now his.

Where This Stands Right Now
The probe is being run out of the Southern District of Florida under Attorney General Todd Blanche’s Justice Department. Its stated theory, described by prosecutors as “far-reaching,” is that officials who investigated Trump over the past decade conspired to deprive him of his civil rights. Former FBI Director James Comey has been under investigation in the same effort since summer 2025. Joseph diGenova, the former Reagan-era U.S. attorney who served as counselor to Blanche and led the Florida probe, resigned last week along with his wife and law partner Victoria Toensing. Within days of his exit, the department served Brennan.
Brennan’s team is fighting on process. Wainstein has argued the department may be steering the matter toward a Florida judge seen as favorable to Trump in past cases, a claim he described as “possible judge shopping.” In July 2026 Brennan sued to force the department to preserve records tied to the investigations of him. Neither move disputes what he told Congress. Both are aimed at where and how he will have to answer for it.
How We Got Here
The Justice Department is examining whether law enforcement and intelligence leaders broke laws or abused power while probing links between Russia and the Trump campaign in 2016, and in drafting the January 2017 intelligence assessment on Russian interference. Brennan, who ran the CIA when that assessment was written, has defended it for years. In 2017 he told Congress the Trump-Russia inquiry was “well-founded.” The false-statements question now before the grand jury turns on what he said about that same assessment when he testified again in 2023.
For readers who watched the Russia investigation consume the first Trump term, the significance is simple. The officials who ran it have never had to answer questions under oath in front of a grand jury. On October 15, one of them will.
What To Watch Next
Watch for whether Brennan moves to quash or narrow the subpoena, whether prosecutors want his documents as well as his testimony, and whether the “judge shopping” argument gets a ruling from the chief judge in Florida. Grand juries work in secret, so credible updates will come from court filings and on-the-record statements, not rumor. The other marker is the witness list. If more former officials from the 2016 and 2017 decisions get the same letter, the probe is broad. If it narrows to Brennan alone, prosecutors may be testing a tighter case built on his own words.
