's Watchdog Has $1.5 Billion in Recommended Savings Still Open
Summary
As of March 31, 2026, 's inspector general counted 628 open audit recommendations spanning reports issued since June 5, 2014 -- and just 70 of them, from 34 reports, carry a quantified dollar figure: more than $1.5 billion in savings the department has not yet realized. In the same report, auditors flagged $95.4 million in Hurricane Sandy transit-grant costs incurred after the money should have stopped.
Where a recommendation goes to wait
The report defines the lifecycle in its own terms: a recommendation opens the day an audit report is issued, stays "unresolved" until DOT and the OIG agree on corrective steps, becomes "resolved," and only closes once DOT provides evidence the steps were actually taken. Nothing in that chain has a statutory deadline. In the same six months this report covers, issued 22 new audit reports carrying 119 new recommendations, with a combined financial impact of $254,659,875 -- a single period's flow next to a backlog that has been accumulating since 2014.
View data as table
| Open backlog (since 2014) | $1.5B+ | 70 recommendations, 34 reports, open as of March 31, 2026 |
|---|---|---|
| New this half-year | $254.7M | 22 reports, 119 recommendations, Oct. 2025-Mar. 2026 |
Most of the backlog isn't even counted in dollars
The $1.5 billion figure is a floor, not a ceiling, on what the backlog is actually worth: it covers only the 70 recommendations could attach a number to. The other 558 -- 88.9% of the open total -- have no dollar estimate in the office's own accounting at all. That doesn't mean they're cheap; it means many findings (a process gap, a missing control, a training requirement never implemented) aren't the kind of thing that reduces to a line item, even when left unresolved for years.
One case in this report: grant money that kept flowing after the deadline
The same report supplies a concrete example of how a recommendation gets made. Reviewing the Federal Transit Administration's oversight of Hurricane Sandy recovery grants, found FTA relied on recipient self-reporting, which "was not sufficient to encourage expedited spending or reduce the risks of ineligible costs," and identified $95.4 million in questioned costs incurred after the grants' periods of performance had already ended. FTA grants with unexpended Hurricane Sandy funds, the report adds, also remain open after the underlying projects are finished -- the same open-ended pattern as the recommendation backlog itself, playing out inside a single grant program.

A separate ledger: what 's investigators recovered
Audits aren't 's only tool. Investigations closed in the same six months produced a total financial impact of $1,250,217,267 -- almost entirely restitution ($1,222,402,423), plus forfeitures and fines -- from 82 investigations and complaints opened, 77 closed, 23 indictments or criminal informations, and 25 convictions. That figure runs through courts, on a case-by-case basis, and isn't part of the audit-recommendation arithmetic above; it's included here because it shows the other half of what the same office does with the same six months -- recovering money after the fact, rather than flagging it before the fact.
The takeaway
- 628 audit recommendations were still open as of March 31, 2026, from reports issued as far back as June 5, 2014 -- and only 70 of them, from 34 reports, carry a quantified dollar figure at all: over $1.5 billion in savings identified but not yet realized.
- That backlog is roughly 5.9 times the $254,659,875 in financial impact from the 22 audit reports issued in just the six months covered by this report -- a rough sense of scale, not a rate, since the two figures sit on different time bases (a multi-year stock vs. a single period's flow).
- One case from this period shows how a recommendation starts: FTA's Hurricane Sandy grant oversight relied on recipient self-reporting, and found $95.4 million in costs questioned after the grants' own performance periods had ended.

The report does not name any individual employee, contractor, or grantee as a wrongdoer in the passages cited here, and neither does this piece.
The 5.9x backlog-to-half-year ratio and the 11.1% share of open recommendations that carry a dollar figure are this outlet's own arithmetic on figures the report states separately (methods and caveats in analysis.json); does not itself state either comparison, and the ratio should be read as a scale comparison across different time bases, not an accumulation or resolution rate. A blind adversarial verifier, working from the primary document alone with no access to this draft, independently checked every itemized fact; see verification.json.

's Office of Inspector General keeps a running ledger of its own unfinished business. As of March 31, 2026, that ledger held 628 open audit recommendations, spanning 182 reports issued since June 5, 2014, according to 's Semiannual Report to Congress⧉ for October 1, 2025-March 31, 2026. Only 70 of those recommendations, from 34 of the 182 reports, carry an estimated dollar figure at all -- and together they total more than $1.5 billion in savings or cost avoidance the department has agreed exists, on paper, but has not yet realized.
