Washington is facing another fight over one of the federal government’s most basic constitutional questions: Who ultimately controls federal spending?
On September 25, 2026, President Donald Trump sent Congress a proposal seeking to rescind $810 million from 11 federal appropriation accounts. The White House described the targeted spending as wasteful or harmful and argued that the administration could use the rescission process under the Impoundment Control Act of 1974 to prevent the money from being spent.
Four days later, the nonpartisan Government Accountability Office reached a different conclusion. GAO said the rescission proposal did not permit the administration to withhold the affected appropriations beyond the end of fiscal year 2026 on September 30 unless Congress completed action rescinding the money.
Now the dispute has moved into federal court. On October 1, California and six other states filed a lawsuit challenging the administration’s withholding of federal funds, including money affected by the September rescission package.
At the center of the controversy is a budget maneuver commonly called a “pocket rescission.” Understanding how it works helps explain why an $810 million spending dispute has become a much larger argument about the separation of powers.
What exactly did the White House propose?
The White House’s September 25 special message formally proposed 11 rescissions totaling $810 million. The affected accounts span the Departments of Commerce, Education, Health and Human Services, Homeland Security, Housing and Urban Development, and Justice, as well as international assistance programs.
The largest proposed rescission is $567 million from a Department of Health and Human Services account involving services for refugees, asylum seekers and other noncitizens. The package also targets funding connected with immigration services, education, minority-business programs, health research and international programs.
The administration argues that the targeted expenditures are unnecessary, duplicative or inconsistent with its policy priorities. Those descriptions reflect the White House’s position on the programs; GAO’s September 29 decision specifically said its legal analysis did not take a position on the merits of the programs themselves.
What is a pocket rescission?
Congress has constitutional authority over federal appropriations. The Impoundment Control Act of 1974 established a process for a president who wants Congress to cancel money that lawmakers have already appropriated.
Under that process, the president may send Congress a special message proposing a rescission. The law provides a period for congressional consideration during which the corresponding money may temporarily be withheld from obligation. If Congress does not complete action on legislation rescinding the money within the statutory period, the funds generally must be made available for obligation.
A pocket rescission attempts to use the calendar differently. If a rescission proposal is submitted shortly before the underlying appropriation expires, the fiscal year can end before Congress’s full consideration period has run. The practical question then becomes whether the executive branch may continue withholding the money until it expires.
That is exactly what happened here. The September 25 proposal arrived only five days before the September 30 end of fiscal year 2026.
What did GAO decide?
On September 29, GAO issued a formal review of the president’s special message. It concluded that all 11 accounts covered by the proposal were scheduled to expire at the end of fiscal year 2026 and that the congressional consideration period would extend beyond that date.
GAO concluded that the Impoundment Control Act does not authorize the president to keep appropriated funds withheld through their expiration simply because a rescission proposal is pending before Congress.
GAO’s reasoning rests on the structure of the 1974 law and Congress’s constitutional power of the purse. In its view, the statute permits temporary withholding while Congress considers a rescission request, but it does not give the executive branch independent authority to make congressionally approved funding disappear through expiration.
GAO also emphasized an important distinction: its conclusion concerned compliance with federal spending law, not whether the programs targeted by the administration are good or bad policy.
What does the White House argue?
The administration takes a broader view of presidential authority under the Impoundment Control Act. It argues that pocket rescissions are among the tools available to a president seeking to reduce spending and that the programs in this package do not warrant continued funding.
The administration attempted a similar strategy in 2025 involving a $4.9 billion foreign-aid rescission proposal. Litigation over roughly $4 billion of that funding reached the Supreme Court, which allowed the administration to continue withholding the disputed money while the litigation proceeded.
That Supreme Court action did not produce a final ruling resolving every legal question surrounding pocket rescissions. The 2026 dispute also involves a different mix of programs, including substantial domestic spending.
The dispute crosses party lines
Opposition to the maneuver has not come exclusively from Democrats.
Republican Sen. Susan Collins of Maine, chair of the Senate Appropriations Committee, criticized the September action and argued that rescinding congressionally appropriated money without legislative approval undermines Congress’s constitutional spending authority. Democratic lawmakers have raised similar objections and sought additional restrictions on the use of pocket rescissions.
Supporters of the administration’s approach focus instead on presidential authority to challenge spending the executive branch considers unnecessary and on the rescission procedures contained in federal law.
Why $810 million could have much larger implications
The immediate dispute concerns $810 million, a small share of total federal spending. The precedent, however, could affect far larger amounts in future budgets.
Congress writes appropriations laws, while executive agencies carry them out. If an administration can effectively prevent appropriated money from being spent by submitting a rescission request shortly before the money expires, presidents could gain greater practical control over which parts of congressional spending laws are implemented.
If the law instead requires the executive branch to make the money available unless Congress affirmatively approves a rescission, the final decision remains with lawmakers.
That difference is why the fight extends beyond the individual programs listed in the September proposal. It raises a broader institutional question about where Congress’s power of the purse ends and presidential authority over execution of the budget begins.
The dispute moves to court
The September 30 fiscal-year deadline has now passed, but the controversy has not.
On October 1, California and six other states filed suit in federal court challenging the administration’s withholding of congressionally appropriated funds. Their lawsuit argues that the administration unlawfully prevented federal money from being spent and asks the courts to address the constitutional and statutory issues surrounding the action.
The filing does not itself resolve the dispute. The administration can contest the states’ claims, and courts may ultimately have to determine how the Impoundment Control Act applies to the challenged funding and what remedies remain available after the fiscal-year deadline.
What happens next?
The immediate September deadline is over, but several questions remain unresolved. Litigation can test the administration’s interpretation of its authority, Congress can consider legislation addressing pocket rescissions, and lawmakers can continue using the appropriations process to define how federal money must be spent.
The political argument over whether these particular programs deserve federal funding is separate from the institutional question at the heart of the case: when Congress has enacted an appropriation that a president opposes, what legal authority does the executive branch have to prevent that money from being spent?
The answer could influence federal spending disputes well beyond this $810 million package.
