Ian Brinksman arrested in Washington, D.C., in defense leaks case
Federal agents took Ian Brinksman into custody in Washington, D.C., on charges of leaking classified defense secrets. The federal case follows an investigation into government materials shared with an online publication writer.
The Department of Justice announced the charges on Friday. FBI investigators accused the 42-year-old contractor of leaking national defense information to his girlfriend. She writes an online publication on Substack.
Brinksman worked for a third-party company. That company provided services to a government agency. Federal agents searched his Washington, D.C., home before taking him into custody.
A September 2026 fundraising article cited by prosecutors claimed the writer published reporting based on classified government assessments. The writer also posted an online invitation asking sources for leaks, the Justice Department stated.
Affidavit quotes match posts on Capital & Empire Substack, a Congress and defense publication written by Aida Chavez. Chavez did not immediately respond to a request for comment. Her past work appeared in The Hill, according to her social media profile.
FBI Director Kash Patel released a statement about the case.
Protecting America’s secrets is a top counterintelligence priority of this FBI – and anyone caught abusing their position of trust within the government by jeopardizing national security and putting our brave warriors at risk will be met with the full weight of justice.
The second Trump administration made prosecuting leakers a priority. Officials threatened prosecution for both government workers and news outlets that share leaks. Former presidents Obama, George W. Bush and Nixon made similar pledges.
In July, the Justice Department moved to subpoena four New York Times reporters. That case involved reporting on a luxury jet from Qatar used as Air Force One.
Federal counterintelligence cases often begin with internal reviews of classified systems. Agencies then refer potential security breaches to the FBI for investigation. Suspects face initial proceedings in federal district court.
Authorities have not yet announced the next Washington, D.C., court date for Brinksman.
