Homeland Security Secretary Kristi Noem has vowed criminal prosecution after the Department of Homeland Security identified what officials described as a “prolific leaker” responsible for repeatedly disclosing sensitive internal information. The case has renewed concerns about internal sabotage and politicization within federal agencies. Noem said accountability is necessary to restore trust and protect national security.
Speaking to Fox News, Noem confirmed that DHS investigators recently identified the individual believed to be behind numerous unauthorized disclosures. She said the leaks compromised law enforcement operations and undermined the department’s mission. According to Noem, the information was shared with media outlets in ways that distorted enforcement efforts and endangered personnel.
The leaks reportedly involved details related to border enforcement, immigration operations, and internal DHS deliberations. Noem stated that the disclosures were not whistleblower activity but deliberate violations of federal law. She emphasized that lawful whistleblower channels exist and that bypassing them carries consequences.
Noem said the department is working closely with federal prosecutors and inspectors general to move the case toward criminal charges. She stressed that leaking classified or sensitive law enforcement information is not protected speech. DHS officials believe the individual acted repeatedly over an extended period, prompting the description of a “prolific” leaker.
The announcement comes amid heightened tensions over immigration enforcement under President Trump. The administration has pushed for stricter border controls, increased removals, and stronger cooperation with state and local authorities. Officials argue leaks have been used to undermine those policies by shaping public narratives and disrupting operations.
Republican lawmakers welcomed Noem’s stance, arguing that federal agencies must not be allowed to operate as partisan actors. They contend unchecked leaking erodes public confidence and weakens the rule of law. Democrats have not publicly commented on the specific case but have historically defended some leakers as whistleblowers.
Noem said the investigation sends a clear message that DHS will not tolerate internal efforts to sabotage enforcement or misuse government information for political purposes.
