The Government Accountability Office said Tuesday that President Donald Trump cannot legally withhold congressionally approved funds until they expire unless Congress itself acts on the requested rescissions, escalating a constitutional fight over executive spending power at the end of the fiscal year. The decision concerns a Sept. 25 presidential message proposing rescissions from 11 appropriation accounts and an Office of Management and Budget directive withholding the affected money from obligation.
The GAO concluded that the Impoundment Control Act does not permit the president to force appropriated funds to expire while Congress considers a rescission request. The agency emphasized that its conclusion addresses the law governing congressional appropriations rather than the merits of the programs Trump wants to cut.
Trump Spending Cuts Face a Legal Deadline
The dispute arises under the Impoundment Control Act of 1974, which created procedures for presidents who want Congress to cancel previously approved spending. A president may send lawmakers a special message recommending rescissions, but the law generally requires the money to remain available unless Congress completes action on legislation canceling it.
The timing is especially important because the affected funds are approaching the end of their period of availability. GAO said the administration cannot keep the money frozen until the fiscal year closes and thereby accomplish through expiration what Congress has not approved through legislation.
The Trump administration argues that the executive branch needs greater control over spending it considers wasteful, unnecessary or inconsistent with presidential priorities. Critics counter that the Constitution gives Congress the power of the purse and that a president cannot cancel appropriations simply by declining to spend them.
GAO Cites the Impoundment Control Act
GAO’s legal conclusion rests on the text and history of the Impoundment Control Act, as well as Supreme Court precedent concerning appropriated funds. The agency said amounts proposed for rescission must be made available for obligation unless Congress passes a rescission bill before the funds expire.
The law was enacted after conflicts between Congress and President Richard Nixon over executive impoundment. Its purpose was to preserve congressional control over spending decisions while still giving presidents a formal process to recommend that lawmakers cancel budget authority.
GAO said permitting a president to withhold money until expiration would effectively allow the executive branch to nullify appropriations without a vote. The agency described that result as inconsistent with both the statute and Congress’ constitutional spending authority.
The White House Has Pursued Broader Spending Rescissions
The Sept. 25 request is part of a larger Trump administration effort to reduce federal spending through rescissions, program cancellations and changes in agency obligations. The White House has argued that many appropriations reflect outdated priorities and that the executive branch should aggressively seek savings where Congress has not already acted.
Those efforts have generated repeated lawsuits and oversight disputes. Federal courts have examined whether agencies can pause grants, redirect appropriated funds or impose new conditions on money Congress designated for specific purposes, while lawmakers from both parties have defended congressional authority in selected cases.
The current GAO decision is narrower than some of those court battles because it focuses specifically on the statutory rescission process. It does not decide whether Congress should cancel the programs at issue, nor does it determine whether any particular expenditure is economically justified.
Congress Could Still Approve the Cuts
GAO’s decision does not prevent Congress from passing legislation rescinding the funds. If lawmakers approve the president’s request through the normal legislative process, the budget authority can be canceled lawfully.
That means the dispute is fundamentally about who has authority to make the final decision when Congress has not acted. The White House can propose cuts and urge lawmakers to approve them, but GAO says the administration cannot achieve the same result unilaterally by withholding the money until the clock runs out.
The practical challenge is that Congress is operating under tight fiscal deadlines. Lawmakers would have to move quickly to enact any rescission legislation before the affected funds expire, while agencies must determine whether to begin obligating money that OMB had previously told them to withhold.
The Fight Could Move to Federal Court
GAO opinions are important interpretations of federal fiscal law, but the agency does not itself issue judicial injunctions. If the administration rejects GAO’s conclusion and continues withholding funds, affected agencies, grant recipients or members of Congress could seek relief in federal court.
A court case would likely focus on statutory language in the Impoundment Control Act and the Constitution’s assignment of spending power to Congress. The administration could argue for a broader understanding of executive authority, while challengers would point to the law’s requirement that appropriated funds remain available absent congressional rescission.
The dispute may also shape future budget negotiations. If courts reinforce GAO’s position, presidents would face stronger limits on using delayed obligations as a substitute for legislative rescissions. If the administration prevails, the executive branch could gain significantly more leverage over spending Congress has already approved.
Power of the Purse Is the Central Issue
The broader significance goes beyond the amount involved in this particular rescission request. The constitutional question is whether Congress’ appropriation laws create binding spending authority that the president must respect unless lawmakers agree to change it.
Supporters of strong executive control argue that presidents need flexibility to prevent waste and respond to changing conditions. Defenders of congressional prerogatives argue that giving presidents unilateral power to cancel appropriations would weaken one of the legislature’s most important constitutional checks on the executive branch.
GAO’s Sept. 29 opinion takes the latter statutory position, concluding that the president may recommend rescissions but cannot force appropriated money to expire while Congress considers the request. Whether the administration complies, seeks a different legislative path or tests the issue in court will determine how quickly the latest Trump spending cuts dispute becomes a broader separation-of-powers case.
