Beginning in March 2025, the Department of Homeland Security under Secretary Kristi Noem subjected employees to polygraph examinations - some reported to last up to roughly six hours - to identify the sources of leaks, and forcibly reassigned senior career staff. Employees and journalists described the measures as a "campaign of fear" that deterred internal dissent and lawful disclosure.

Beginning in March 2025, the Department of Homeland Security under Secretary Kristi Noem began subjecting employees to polygraph examinations - reported in some cases to last up to roughly six hours - in an effort to identify who was disclosing information to the press, and forcibly reassigned senior career officials. A Guardian investigation published July 11, 2026 documented the practices in detail, describing a sustained "campaign of fear" that deterred internal dissent and lawful disclosure across the department.

The polygraph-for-leakers program was first disclosed in March 2025 and expanded over the following year. Reporting described career staff being moved out of their posts and employees being questioned under polygraph about their contacts with journalists, with the stated purpose of finding the sources of leaks.
