The House fiscal year 2027 legislative branch appropriations bill includes two provisions that, taken together, would fundamentally weaken Congress’s ability to control how taxpayer dollars are spent and give the executive branch far more leeway to ignore the law.

First, the bill cuts the Government Accountability Office (GAO), Congress’ investigative arm, by $200 million, a roughly 25 percent reduction that could eliminate more than 1,000 staff. Second, Section 116 would effectively block GAO from using its remaining funds to bring enforcement actions under the Congressional Budget and Impoundment Control Act (ICA) unless Congress first passes a concurrent resolution authorizing the lawsuit. A similar proposal surfaced in last year’s appropriations process but was ultimately dropped. It should be dropped again.

On their own, each provision is concerning. Together, they would dismantle a central enforcement mechanism Congress created 50 years ago to help ensure its spending decisions are carried out. To understand why this matters, consider what happened last year.

The ICA was enacted after President Nixon refused to spend funds Congress had already appropriated, a practice known as impoundment. The law sets strict limits on when the executive branch can withhold funding and designates the Comptroller General, who heads GAO, as the enforcement authority when those limits are violated.

In 2025, the Trump administration repeatedly tested those limits. By May of last year, GAO had opened 39 investigations into potential illegal impoundments. Over the following months, it found violations across multiple agencies. In each case, the conclusion was straightforward. Congress had already approved the funding through appropriations legislation, and the executive branch does not have the authority to unilaterally refuse to spend it.

Then came a pivotal court decision. In Global Health Council v. Trump, the D.C. Circuit Court made clear that private parties cannot sue to enforce the ICA. Only the Comptroller General can. The ruling clarified how the system is supposed to work. Congress writes the laws, the executive branch implements them, and GAO serves as the independent enforcement backstop when disputes arise. That adversarial structure is intentional. Impoundment disputes are fundamentally conflicts between the legislative and executive branches, and Congress is neither structured nor nimble enough to adjudicate those disputes in real time on its own.

Section 116 would break that system. Under the provision, GAO could not bring an enforcement action unless Congress first approves it through a concurrent resolution. In practice, that means a majority in both chambers would have to restate and reauthorize spending Congress already approved before GAO could sue the administration for violating the law.

Lawmakers in the 1970s understood that Congress might be reluctant to confront a president of the same party. That is why they created an independent enforcement mechanism in the Comptroller General. If lawmakers want to revisit the ICA itself, they should pursue changes through separate authorizing legislation, not slip them into an annual appropriations bill.

The proposed budget cut compounds the problem. Investigating impoundments is resource-intensive work requiring legal analysis and persistent engagement with agencies that often resist oversight. Cutting GAO’s staff by a quarter would inevitably reduce its capacity to conduct that work, along with the broader oversight and accountability responsibilities that are its bread and butter.

The committee report accompanying the bill repeatedly praises oversight, transparency, accountability, and the need to maintain Congress’s analytical capacity. It even highlights the importance of independent watchdogs free from political interference. Yet the bill itself would slash GAO’s budget by nearly 25 percent while restricting one of its core enforcement powers. Congress cannot strengthen oversight by defunding and restraining the institution charged with carrying it out.

The implications go well beyond GAO. The appropriations process rests on a basic premise: Congress decides how public money is spent, and the executive branch carries out those decisions. The ICA was enacted to reinforce that principle after it was repeatedly ignored. The law also created a formal process for presidents to request that Congress cancel previously appropriated funding through rescissions, which Congress can approve or reject. In fact, Congress approved a rescission just last year.

If these provisions become law, the message to any administration, current or future, is clear. Withhold funds if you want, and unless Congress chooses to intervene, there may be no meaningful consequence.

That is not fiscal discipline. It is a shift in power. Article I of the Constitution vests Congress with the power of the purse, yet over time lawmakers have too often acquiesced, frequently for political convenience, allowing that authority to migrate to the executive branch. The provisions in this bill are clear examples of that drift. The power of the purse depends on enforcement. Without it, appropriations laws become little more than suggestions.

Lawmakers should reject this approach. That means striking Section 116 and restoring GAO’s funding. Oversight only works if it is independent and can operate without political permission. Congress created GAO to serve as that backstop. It should not dismantle it now.
