Ever get that feeling that someone, somewhere, is double-checking the receipts? In the federal government, that’s not just a feeling. It’s a massive, multi-billion dollar operation involving over 70 different offices. Honestly, if you’re looking for a list of inspectors general, you’re basically looking at the immune system of the United States government. They find the waste. They catch the fraudsters. And sometimes, they get caught in the middle of massive political firestorms.
It’s January 2026, and the landscape for these watchdogs has shifted quite a bit. We’ve seen a wave of new appointments, a lot of "acting" tags finally getting replaced with permanent names, and a few familiar faces moving into high-stakes roles.
The Heavy Hitters: 2026’s Most Influential IGs
The big Cabinet departments usually get the most headlines because, frankly, that's where the most money is. If you're following the money, you're following these names.
Anthony D’Esposito just took the reins at the Department of Labor (DOL-OIG) in early January 2026. A former congressman, his move into the IG world is one of those things people are talking about because it’s a bit of a shift from the typical "career auditor" path.
Then you’ve got Thomas March Bell over at Health and Human Services (HHS-OIG). He started late in 2025. HHS is a beast—think Medicare, Medicaid, and all that pandemic oversight that still has a long tail of audits. Bell has a history with the agency, which helps when you’re trying to navigate one of the largest budgets in the world.
At the Department of Agriculture (USDA-OIG), John Walk officially started his term on January 5, 2026. Agriculture might sound sleepy to some, but it’s a massive target for fraud in food programs and farm subsidies.

The Defense and Intelligence Gatekeepers
Security is its own world. These IGs don't just look at money; they look at secrets.
- Department of Defense (DOD-OIG): Currently, Steven A. Stebbins is holding down the fort as the Acting IG. The Pentagon is notorious for being the only agency that has struggled to pass a full audit, so this seat is always a hot one. Platte Moring has also been a major name in the confirmation pipeline for this orbit.
- Intelligence Community (ICIG): Christopher Fox took over in October 2025. If there's a whistleblower in the spy world, Fox is the one who gets the call.
- CIA-OIG: Peter Thomson moved into this role in September 2025.
- NSA-OIG: Kevin Gerrity is currently the Acting IG here.
Why Does This List Keep Changing?
You've probably noticed a lot of "Acting" titles. That’s the reality of the list of inspectors general. Getting a permanent IG confirmed by the Senate is often a slow, grinding process. An "Acting" IG has the power to sign reports and run investigations, but they don't have the same job security as a presidentially-appointed, Senate-confirmed official.
The Council of the Inspectors General on Integrity and Efficiency (CIGIE) is the group that tries to keep all these different offices on the same page. Think of it as the "IG for the IGs." It’s currently led by an executive team including Andrew Cannarsa as Executive Director. They run Oversight.gov, which is basically a giant database where you can find every public report these offices put out.
The New Guard of 2026
Here is a quick rundown of some other major players who are currently in the driver's seat as of mid-January 2026:
Department of Veterans Affairs (VA-OIG): Cheryl L. Mason. She’s been in the mix since August 2025, focusing on healthcare quality and the massive backlog of claims that always seems to plague the VA.

Small Business Administration (SBA-OIG): William Kirk. Appointed in January 2026. He’s got his hands full with the aftermath of pandemic-era loan fraud investigations, which are still very much alive.
Department of Justice (DOJ-OIG): This is a weird one. Don R. Berthiaume is the Acting IG. This office is the one that investigates the FBI and the DEA. It’s arguably the most scrutinized IG office in the country.
Homeland Security (DHS-OIG): Joseph V. Cuffari remains in this role. He’s been there since 2019, making him one of the longer-tenured IGs on the current list, though his time there has certainly not been without its share of public controversy and debate.
The Role You Didn't Know Existed
Most people think IGs just sit in offices and look at spreadsheets. Kinda. But they also have armed special agents. When someone steals millions from the government, the OIG agents are often the ones kicking in the door.
Take the Social Security Administration (SSA-OIG). Currently led by Michelle L. Anderson (Acting), they spend a huge amount of time chasing down people who are collecting benefits for deceased relatives. It’s gritty work.

Or look at NASA-OIG, where Robert Steinau is the Acting IG. They have to make sure the private companies getting billions for space travel aren't cutting corners that could cost lives.
What Most People Get Wrong About IGs
A common mistake is thinking IGs work for the head of the agency. They don't. They work within the agency, but they report to both the Agency Head and Congress. This "dual reporting" is what makes them independent. They are the only people in a department who can tell the Secretary "you’re doing this wrong" without getting fired on the spot—at least, in theory.
The law that started it all was the Inspector General Act of 1978. Before that, oversight was a mess. Now, it’s a standardized system. But even with a 40-year-old law, the politics of 2026 make the job harder than ever. When an IG releases a report that makes a department look bad, the political blowback is instant.
Actionable Steps for the Public
If you actually want to use this information, don't just look at the names. Use the tools.
- Check Oversight.gov: This is the gold standard. You can search by agency or by topic (like "COVID fraud" or "cybersecurity"). It's the most transparent part of the government.
- Use the Hotlines: Every single one of these IGs has a "Hotline." If you work for the government or a contractor and you see something shady, you don't go to your boss—you go to the OIG. Most allow anonymous reporting.
- Read the Semiannual Reports: Every six months, each IG has to send a summary of their work to Congress. These are surprisingly readable and give you a "state of the union" for that specific agency.
- Follow the Vacancies: If you’re a policy wonk, watch the Senate Oversight Committee. When a new name is nominated for the list of inspectors general, that’s your chance to see what the administration’s priorities are for that agency.
The system isn't perfect. Vacancies stay open too long, and "acting" IGs can sometimes feel pressured. But without this list of watchdogs, the federal budget would essentially be a black hole. Whether it's Fara Damelin at the FCC or Jennifer L. Fain at the FDIC, these are the people making sure your tax dollars don't just vanish into thin air.
The best way to stay updated is to monitor the official CIGIE directory, as leadership changes can happen with a single Friday afternoon press release. Knowing who's in charge is the first step in holding the government accountable.
