DHS watchdog tells Congress Noem is blocking 11 investigations
Noem asked for a list of all criminal investigations against her agency
On March 4, 2026, DHS Inspector General Joseph Cuffari sent a letter to Congress that was unusual in its candor: he listed 11 specific instances in which DHS had blocked his office from accessing witnesses, documents, or ongoing investigations, and stated that in each case, his office had not been told why access was being denied. Timing was not coincidental. Cuffari sent the letter the day after Noem testified before both Senate and House Judiciary Committees, while she was simultaneously defending DHS operations from a different angle. His letter landed in senators' hands while she was still on Hill. Sen. Thom Tillis (R-NC), who had already been publicly demanding accountability on Noem OIG obstruction since January, held up the letter during the Senate Judiciary hearing and told Noem directly: 'This failure of leadership is grounds for resignation.' He had already threatened to hold all DHS nominees unless obstruction ended. The Hill CNBC

Key People
10JC
Joseph Cuffari
DHS Inspector General
Cuffari wrote March 4 letter to Congress documenting 11 instances of DHS obstruction and sent it day after Noem congressional testimony. His survival of January 2025 IG purge that removed 17 others made his continued service notable, and his letter to Congress clearest act of institutional self-defense available to him without resigning.
Kristi Noem
Former DHS Secretary (fired March 5, 2026)
Noem personally requested list of all pending OIG criminal investigations, request that itself raised ethical concerns, and her agency blocked Cuffari access in 11 active cases. She was fired day after Cuffari letter reached Congress, with obstruction cited as one factor in her dismissal.
TT
Thom Tillis
U.S. Senator (R-NC), Senate Judiciary Committee
Tillis held up Cuffari letter during Senate hearing, called obstruction grounds for resignation, and had been threatening to block all DHS nominees since January over same issue. His persistence gave obstruction story its political legs: it was Republican senator, not Democrats, who made OIG blockade firing offense.
Chuck Grassley
U.S. Senator (R-IA), Senate Judiciary Committee; longtime defender of IG independence
Grassley joined Tillis in raising obstruction concerns, giving issue rare bipartisan Senate weight. His decades-long record of defending inspector general authority across administrations of both parties made his involvement significant: this was not partisan attack but principled institutional defense.

Renee Good
U.S. citizen killed during Operation Metro Surge, Minneapolis, January 2026
Good death during ICE operations in Minneapolis was among 11 investigations Cuffari office was blocked from accessing. No criminal referral had been made for her death as of time of Noem firing. Her family testified before Congress about killing; no accountability process had formally advanced.
AP
Alex Pretti
U.S. citizen shot by Border Patrol agents, Minneapolis, January 2026
Pretti was shot by two CBP officers during same Minneapolis operation. Noem called him domestic terrorist at press conference without evidence to support that characterization, claim she refused to retract under Senate questioning. His death was among OIG investigations blocked from proceeding.
Donald Trump
President of the United States
Trump fired 17 inspectors general on night of January 20, 2025, within hours of his inauguration, in mass removal that courts were still adjudicating. His tolerance of Noem OIG obstruction across following weeks set administrative tone: inspector generals operated at pleasure of officials they were supposed to oversee.
Pam Bondi
U.S. Attorney General
Bondi DOJ holds referral authority for criminal prosecution of officials who violate Inspector General Reform Act. She had not publicly commented on Cuffari letter and had not announced any investigation into obstruction. Her silence is closing link in accountability loop.
IG
Inspector General Reform Act of 2008
Federal statute prohibiting executive branch interference with IG investigations
Act explicitly bars officials from obstructing IG access to witnesses and records, making such obstruction potentially criminal. Cuffari letter was formal invocation of that statute protections. Without DOJ referral, statute enforcement mechanism is politically inert.
Gregory Bovino
CBP Operations Commander, Operation Metro Surge, Minneapolis
Bovino commanded Minneapolis enforcement operation under which both Renee Good and Alex Pretti were killed. Congressional sources reported that Bovino himself was among subjects of blocked OIG investigations. His removal from operational command and scope of investigations into his conduct are among questions Cuffari obstruction prevented Congress from answering.
What you can do
Contact your senators to demand DHS cooperate with its inspector general
civic action
Congress created inspectors general to provide independent oversight of executive agencies. When an agency blocks an IG from investigating — especially when the IG says one blocked investigation has national security implications — Congress has both the authority and responsibility to intervene.
Read the Inspector General Reform Act to understand legal protections
research
The Inspector General Reform Act of 2008 is the primary law protecting inspector general independence. Understanding what it requires — and what enforcement mechanisms exist — gives citizens a factual basis for demanding accountability.
Track the DHS OIG's published reports and investigation status
research
The DHS OIG publishes its completed reports, audits, and investigations publicly. Tracking what reports have been published and what investigations remain open — particularly in the context of 11 blocked access requests — helps citizens identify gaps between what the IG is investigating and what it's able to complete.
