DHS watchdog tells Congress Noem is blocking 11 investigations

DHS Inspector General JCJoseph Cuffari sent a letter to Congress describing 11 separate instances in which DHS leadership had refused his office access to records, databases, or personnel needed to complete ongoing investigations. The letter became public during Noem's Senate Judiciary hearing on March 3-4, 2026.

Cuffari said that in one case, DHS had blocked a criminal investigation with 'national security implications,' calling this instance 'particularly egregious' — language unusual in OIG correspondence that signals the obstruction went well beyond bureaucratic foot-dragging.

Noem personally asked Cuffari to provide her with a complete list of all pending OIG investigations, including active criminal matters. Cuffari declined. The request is significant: if a secretary knows the full list of investigations against her agency, she can identify and obstruct the most threatening ones before findings are completed.

Inspectors general are independent watchdogs inside federal agencies. They can't be fired without cause and their reports go to Congress, not just to the agency head. But their independence depends on agency cooperation. When access to records is blocked, the IG's primary recourse is complaining to Congress — exactly what Cuffari did.

Sen. Thom Tillis (R-NC) — a Republican — cited the Cuffari letter during Noem's Senate Judiciary hearing, saying her refusal to cooperate with the watchdog showed 'a failure of leadership' and was grounds for her resignation. His critique was among the most pointed Republican criticisms of Noem across both days of testimony.

The Inspector General Reform Act of 2008 requires federal agencies to cooperate fully with OIG investigations and prohibits interference. Willful obstruction can constitute a criminal violation, though prosecutions of agency heads for obstructing their own IG are historically rare.

The obstruction pattern exists alongside a specific accountability failure: the DHS OIG was simultaneously being asked to investigate ICE excessive force during Operation Metro Surge in Minneapolis, where two people were killed. Blocking the IG from records while the agency faces scrutiny for deaths is obstruction of accountability for those deaths.

The DHS is operating under a funding lapse with approximately two-thirds of staff furloughed. The OIG's ability to push back against document denials is directly reduced by that lapse — fewer investigators, less capacity, and a weakened institutional hand.

The Cuffari letter is distinct from a criminal referral — it's a notification to Congress that the IG's independent function is being compromised. Congress can respond with hearings, subpoenas, legislation, funding cuts, or a vote to remove the secretary. Each option requires majority votes.

Trump fired 17 inspectors general in January 2025 without cause. Cuffari was not among them — he is a Trump-era holdover. But the pattern of 11 access denials in a single letter signals that even a surviving IG faces sustained institutional pressure that limits his ability to function.
