Each week, The Investigative Journal tracks the audits, evaluations and document releases that put government performance on the public record. The week of June 15, 2026, belonged almost entirely to the federal inspectors general, who posted a dense cluster of new reports to Oversight.gov. The headline number came from the Postal Service watchdog, which estimated that counterfeit stamps cost the mail system more than $349 million in a single year. Below, ten notable releases, grouped by theme, with links to the source documents.
Financial Integrity and Improper Payments
The most striking dollar figure of the week came from the U.S. Postal Service Office of Inspector General, which issued an audit titled simply “Counterfeit Stamps” on June 16 (Report No. 25-121-R26). The Postal Service delivers more than 108 billion pieces of mail a year, and each piece requires an approved stamp or other indicator of payment. The audit found that the agency’s efforts to keep counterfeit postage out of that stream remain limited, with “no substantive approach to identify counterfeit stamps in the Postal Service network.”
According to the report, the Postal Service has not developed a comprehensive, risk-based strategy for detecting and mitigating counterfeit stamps, did not set mail-processing equipment to a detection level capable of catching them, and has no identification capability at other points where mail enters the system. Auditors estimated those shortfalls produced more than $349 million in revenue loss and left roughly $1.7 billion in revenue at risk in fiscal year 2026. The report also noted that the Postal Service takes more than twice as long as comparable companies to disable online counterfeit-stamp schemes, citing legal considerations.
The inspector general made four recommendations, and Postal Service management agreed with all four. The figures are estimates drawn from sampling and modeling rather than a precise accounting, and the full methodology is laid out in the published report (PDF). For a self-funded agency that has struggled with recurring losses, even an estimated nine-figure leak in postage revenue is a finding that merits follow-up.
Improper payments surfaced again in a June 17 release from the Department of Justice Office of Inspector General, which audited the department’s fiscal year 2025 compliance with the Payment Integrity Information Act of 2019 (Report No. 26-063). That law requires federal agencies to identify programs susceptible to improper payments, estimate the dollars involved and report their findings. The audit evaluates whether the Justice Department met those reporting requirements; the OIG’s specific conclusions are detailed in the report itself (PDF). Compliance audits of this kind are routine, but they are the mechanism Congress relies on to gauge whether agencies are tracking the roughly hundreds of billions of dollars in improper payments the government estimates each year.
A related farm-payment review came from the Department of Agriculture Office of Inspector General, which on June 16 published an assessment of the Farm Service Agency’s handling of applications for the Emergency Commodity Assistance Program — a payment program intended to deliver economic assistance to agricultural producers. The assessment examines how the agency processed those applications, a useful baseline for anyone tracking the integrity of emergency farm spending.
National Security and Insider Risk
One of the week’s more revealing evaluations came from the Office of Inspector General for the Federal Reserve Board and the Consumer Financial Protection Bureau. Issued June 15 (Report No. 2026-MO-B-009R), the evaluation concluded that the central bank “can strengthen its process to monitor and mitigate international travel risks” for employees who travel abroad or carry Board devices to high-risk and restricted countries.
The report’s six recommendations describe a counterintelligence and insider-risk gap at an institution that sits on some of the most sensitive monetary-policy and financial-system information in the government. Among them: develop pre-travel threat briefings, build a program to aggregate and analyze foreign-travel data from the Board’s reimbursement, security-clearance and device-request systems, reconcile unreported travel by clearance holders, and conduct trend analysis to flag “suspicious travel patterns” for escalation to the Board’s insider-risk program. The OIG also urged the Board to determine which positions should be required to report personal international travel before departure based on their access to sensitive information. All six recommendations remain open, according to the inspector general’s posting.
Cybersecurity hygiene drew a separate Justice Department audit. On June 16 the DOJ OIG released an audit of the department’s information system inventory management — the unglamorous but foundational task of knowing exactly which information systems an agency operates. An incomplete or inaccurate system inventory is a recurring weakness across the federal government, because security controls cannot be applied to assets an agency does not know it has. The audit’s findings and recommendations are set out in the published report.
Public Safety and Justice
The Department of War Office of Inspector General — the Pentagon’s watchdog, now issuing reports under the “DOWIG” designation — published an evaluation on June 17 of how the military criminal investigative organizations handle cold-case murder investigations (Report No. DOWIG-2026-091). Those organizations, which include the service-branch investigative commands, are responsible for unsolved homicides involving service members and their families. The evaluation examines how such long-dormant cases are managed and prioritized, a subject of long-standing concern to military families seeking resolution. The detailed findings are available in the report (PDF).
At the local level, the Justice Department OIG released an audit of the Broward Sheriff’s Office in Florida on June 17 (Report No. 26-065), examining the agency’s use of money received through the federal Equitable Sharing Program. That program distributes proceeds from federal asset forfeitures to participating state and local law-enforcement agencies, which must spend the funds within defined rules and report on their use. Periodic audits of recipients are how the department checks that forfeiture dollars are spent as required; the specific results for Broward County are documented in the audit (PDF).
Environment and Infrastructure
The EPA Office of Inspector General inspected Infrastructure Investment and Jobs Act-funded cleanup work at the Diaz Chemical Corp. Superfund site in Holley, New York, in a report dated June 16 (Report No. 26-E-0036). The inspection set out to determine whether the agency is using infrastructure-law money to advance remediation and whether site-safety measures protect public health and the environment.
The inspectors found that the EPA “has acted swiftly to address past complaints from the public,” but recommended that the agency conduct community interviews during its five-year reviews to confirm there are no outstanding community concerns, and that it update its community-involvement plan and make it publicly available. The takeaway is comparatively favorable to the agency on the substance of the cleanup, while flagging community engagement as the area most in need of attention. A parallel infrastructure-spending question came from the Tennessee Valley Authority OIG, which on June 12 posted an evaluation of contractor rework within TVA’s nuclear program — work that has to be redone, at potential cost to ratepayers, when it is not completed correctly the first time.
Technology and Taxpayer Services
The Treasury Inspector General for Tax Administration rounded out the week with a June 15 audit, “Opportunities Exist to Improve the Quality of Chat Applications” (Report No. 2026-308-029), examining the IRS’s growing reliance on online chat tools to answer taxpayer questions. As the agency steers more taxpayers toward automated and live-agent chat to reduce call-center wait times, the quality and accuracy of those tools directly shapes the public’s experience of tax administration. The audit makes nine recommendations, signaling a substantive list of fixes; the specifics are in the published report (PDF).
Records That Warrant Deeper Investigation
Three of this week’s releases stand out as candidates for sustained reporting. The Postal Service’s estimated $349 million counterfeit-stamp loss is the clearest: the figure is large, the agency concedes it cannot currently quantify the problem inside its own network, and the dynamics of overseas counterfeit-stamp supply chains are a story that runs well beyond a single audit. The Federal Reserve’s international-travel security gaps deserve a closer look as well, given the sensitivity of the information Board employees handle and the explicit reference to monitoring for suspicious travel patterns. And the Broward County equitable-sharing audit fits a broader accountability beat: asset-forfeiture revenue is a recurring source of friction between federal rules and local spending, and recipient-agency audits are where those tensions become visible.
