The FBI arrested a CIA contractor in Washington on Friday and charged him with leaking classified national defense information to a romantic partner who publishes a Substack newsletter, according to the Justice Department.
Ian A. Brinksman, 42, of the District of Columbia, was taken into custody after agents searched his home and was charged by criminal complaint with unlawfully transmitting national defense information, the Justice Department said in a statement. The complaint was filed in the Eastern District of Virginia, according to court records posted by the department.
“As alleged, Brinksman reached far outside his own duties to obtain some of our Nation’s most closely held secrets and handed them to a romantic partner he knew intended to publish them,” said Assistant Attorney General John A. Eisenberg. “That is not carelessness. It is a… https://t.co/ra3e3a4eut

According to the Justice Department, Brinksman began working for a U.S. government agency in 2020 and in 2022 moved to a contractor, identified in court papers as “Company 1,” that serves the same agency, where he worked as a systems integration developer. Prosecutors say he held a Top Secret clearance with Sensitive Compartmented Information access the entire time. CIA Director John Ratcliffe said in the department’s statement that the man arrested “provided services to CIA.”
The complaint alleges Brinksman had an ongoing personal relationship with a person who runs a Substack publication, referred to in court papers as “Individual 1.” According to the Justice Department, a fundraising post attributed to that person in September 2026 claimed they had “published reporting based on classified” agency assessments, and the person wrote on social media, “I also accept leaks.”
Investigators allege that on at least five occasions in 2026, the Substack published articles containing information that mirrored classified reports, some marked Top Secret, Reuters reported. The FBI affidavit lays out phone calls between Brinksman and Individual 1 that came shortly before or after he accessed those reports in a classified database, according to the court filing. In one example cited in the affidavit, Brinksman allegedly accessed a Top Secret report on Oct. 1, left his building and spent about 47 minutes on the phone with Individual 1, and a Substack article with similar content was posted on or about Oct. 5.
Top officials did not mince words. “The FBI arrested the subject after he was caught allegedly betraying his oath and leaking classified defense information,” FBI Director Kash Patel said in the Justice Department statement. “Protecting America’s secrets is a top counterintelligence priority of this FBI.”
Attorney General Todd Blanche said the allegations “reflect the behavior of a government contractor who exempted himself from a federal law governing the protection of classified information,” according to the statement.
“As alleged, Brinksman reached far outside his own duties to obtain some of our Nation’s most closely held secrets and handed them to a romantic partner he knew intended to publish them,” Assistant Attorney General for National Security John A. Eisenberg said in the statement and in a post on X. “That is not carelessness. It is a betrayal of his oath and the American people.”
Ratcliffe said there is “absolutely zero tolerance for leaking,” warning in the department’s statement that unauthorized releases endanger “intelligence sources, ongoing operations, and our officers.”
The FBI’s Chicago Field Office is leading the investigation with help from the Washington Field Office, the Justice Department said. Newsweek reported that Brinksman faces the charge after the search of his residence, and the case now moves through federal court in Virginia.
The arrest comes as the administration has vowed to crack down on leaks of classified material. A criminal complaint is only an allegation, and Brinksman is presumed innocent unless and until proven guilty in court, the Justice Department noted.
