The mechanism this report describes is quiet by design.
An inspector general's office decides for itself what to investigate - as the report puts it, 'Investigations are mostly discretionary, left to the OIG's judgment as to which are necessary or desirable' [1].
Which means when the office shrinks, nothing visible breaks. No case is dropped on a courthouse step. The investigation simply never opens, and nobody outside can point to the thing that did not happen.
The Partnership for Public Service counted what can be counted.
Cabinet-department inspectors general produced 6 percent fewer audits and 25 percent fewer investigative reports in the first half of fiscal 2026 than their own fiscal 2020-2024 average. Their workforces were 19 percent smaller in May 2026 than in December 2024 [1].
The report draws the line between the two directly: the three offices with the steepest staffing losses had the largest drops in investigative reports [1]. That is as close to a controlled comparison as this subject allows.
The report's own framing is careful: 'Inspectors general are the mechanism by which the executive branch examines itself, and the volume of that examination has declined sharply in a single year' [1].
The line that converts the statistic into its meaning: 'Every report that did not happen represents oversight that did not occur' [1].
There is a benign reading available, and honesty requires stating it. Fewer staff producing fewer reports is what anyone would predict, and a government determined to shrink itself will shrink its watchdogs along with everything else.
The number that resists the benign reading is the asymmetry.
Audits - the scheduled, mandatory work - fell 6 percent. Investigations - the discretionary work, the kind that follows a tip or a suspicion - fell 25 percent.
When an office is cut, it protects what it must do and sheds what it may do.
What it may do is the part that catches people.
