Trump claims he can end government shutdowns forever, but constitutional law and federal budget requirements say otherwise. The president does not have the unilateral power to prevent shutdowns or fund the government without Congress passing appropriations bills. A shutdown occurs when Congress fails to pass funding legislation, and only Congress can end it by passing those bills and sending them to the president for signature. This fundamental separation of powers has remained unchanged for over 200 years, despite Trump’s recent policy proposals and executive orders attempting to circumvent it.
The recent 43-day government shutdown that ended in November 2025—the longest in U.S. history—illustrated exactly how these dynamics work. Trump signed a funding bill to end that shutdown, but he had no ability to end it himself. Without congressional action, no president can unilaterally restore funding to federal agencies or order employees back to work. Understanding what budget law actually requires exposes the gap between Trump’s claims and constitutional reality.

What Budget Law Actually Requires to Fund the Government
Federal law is clear: only Congress has the power of the purse. The Constitution explicitly grants Congress the authority to “lay and collect Taxes” and “appropriate Money from the Treasury.” This means that before a single dollar can be spent by any federal agency, Congress must pass an appropriations bill that specifically authorizes that spending. The president can sign or veto that bill, but the president cannot create spending authority on their own. When Congress and the president cannot agree on a funding bill before the fiscal year begins, a shutdown automatically occurs. Federal agencies must stop non-essential operations, furlough workers, and freeze spending. The government cannot restart until Congress passes a new continuing resolution or appropriations bill.
For example, when the 43-day shutdown began, federal agencies immediately halted operations because there was no legal authority to spend money. trump could not have restarted the government through executive order or policy change—Congress had to act first. This process applies regardless of the president’s party, priorities, or negotiating position. A Republican president faces the same constraints as a Democratic one. The only exception is in true emergencies where Congress has previously authorized emergency spending, but routine government funding cannot proceed without annual appropriations.
The Constitutional Limits on Presidential Power During Shutdowns
The president’s authority is limited by the separation of powers, a principle established more than two centuries ago. While the president controls how agencies spend money within Congress’s appropriations, the president cannot appropriate new money or override Congress’s funding decisions. This is not a quirk of law—it is the foundational architecture of American government designed to prevent any single branch from controlling all spending. Trump’s recent proposal to end the Senate filibuster rule would make it easier to pass continuing resolutions with 51 votes instead of 60.
However, this would not give Trump power over shutdowns; it would only change the threshold within Congress. Congress would still need to vote and pass funding bills. The president would still need to sign them. A shutdown would still occur if Congress and the president cannot reach agreement, regardless of filibuster rules. Changing the filibuster is a congressional action, not something the president can do unilaterally, and even if successful, it would not grant the president shutdown-ending power—it would only make it easier for Congress to pass bills without bipartisan support. The Framers deliberately kept this power with Congress because they wanted to ensure that the legislature, not the executive, controlled the nation’s finances. This principle has held through every shutdown in American history.
The Recent 43-Day Shutdown and Trump’s Proposal to End the Filibuster
In November 2025, Trump signed a funding bill ending a 43-day government shutdown, the longest in U.S. history. The fact that Trump had to wait for Congress to act—and that the shutdown lasted 43 days—illustrates the core problem with his claim that he can end shutdowns forever. He cannot end a shutdown by declaring it over. Congress must pass funding legislation first. During those 43 days, Trump had no unilateral option to restore government operations, even though he is the president and opposed to shutdowns. Trump has proposed that the Senate eliminate its filibuster rule, which currently requires 60 votes to pass most legislation, including continuing resolutions.
If the filibuster were eliminated, the Senate could pass funding bills with 51 votes. This would make it harder for the minority party to block funding bills through obstruction. However, this proposal reveals the actual problem: shutdowns are not a presidential problem that a president can solve alone. They are a congressional problem requiring congressional solutions. Even if the filibuster were eliminated, shutdown disputes would persist if the president and Congress disagree on policy riders or spending levels. The 43-day shutdown happened not because of procedural rules, but because of fundamental disagreement over how much to spend and on what priorities. Changing the filibuster rule would require Senate Republicans to vote to change their own chamber’s rules—something Trump cannot do alone. And even if successful, shutdowns could still occur if the House and Senate remain divided or if the president vetoes bills he receives.
The Antideficiency Act Obstacle to Trump’s Executive Orders
Trump has attempted to bypass congressional appropriations through executive action. In 2026, Trump signed an executive order directing the Department of Homeland Security to pay its employees during a government shutdown. However, this order violates the Antideficiency Act, a 150-year-old law that explicitly prohibits federal agencies from spending money without a congressional appropriation. The order cannot be executed. The DHS cannot pay workers without Congress appropriating the funds first. This illustrates a critical limitation that Trump’s claims ignore: no executive order can override the Antideficiency Act or the Constitution.
An executive order is not law; it is an instruction from the president to the executive branch. But executive branch agencies cannot obey an order that violates federal law. The Antideficiency Act has teeth: federal employees who spend appropriated money without authorization can face criminal penalties, and agency leaders can be held liable. DHS officials cannot legally pay their workforce based solely on Trump’s executive order without congressional appropriation, even if the president demands it. The 150-year legal pedigree of the Antideficiency Act reflects a long-standing principle: Congress controls the budget, and that principle is not subject to presidential override. This is why Trump’s proposal to end shutdowns through executive action fails at the most basic legal level.
Why the Filibuster Rule Matters—And Why It’s Not a Shutdown Solution
Trump’s proposal to eliminate the Senate filibuster is presented as a way to “end shutdowns forever” by allowing funding bills to pass with 51 votes instead of 60. The logic is that if Republicans control the Senate, they could pass funding bills without Democratic votes, preventing Democratic obstruction. But this misunderstands what causes shutdowns and how budget disputes actually work. Shutdowns occur when there is disagreement between the House, Senate, and president over spending levels or policy riders attached to funding bills. The filibuster does not cause these disagreements; it only makes them harder to resolve. Even with the filibuster eliminated, shutdowns would still happen if the House and president disagree, or if the Senate majority and president disagree, or if Democrats control either chamber.
For example, during the 43-day shutdown in 2025, Trump himself was at the center of negotiations with Congress—the shutdown occurred not because of obstruction, but because of fundamental disagreement over funding priorities. Eliminating the filibuster would not have prevented that shutdown; it might have accelerated it. Additionally, eliminating the filibuster is a congressional action that Trump cannot perform unilaterally. Senate Republicans would have to vote to change their own chamber’s rules. And once the filibuster is gone, it remains gone. If Democrats later control the Senate, they would have the same 51-vote power to pass funding bills, potentially causing shutdowns aligned with Democratic priorities rather than Republican ones.
The Real Cause of Government Shutdowns
Government shutdowns are fundamentally about disagreement, not procedure. They occur when the president and Congress—or different chambers of Congress—cannot agree on how to fund the government. Sometimes the disagreement is over overall spending levels. Sometimes it is over policy riders, such as immigration restrictions or environmental regulations attached to funding bills. Sometimes it is about precedent and leverage in future negotiations.
The 43-day shutdown in November 2025 is a case in point. It lasted that long because Trump and Congress could not agree on the terms. Once they reached an agreement, Trump signed the bill and the shutdown ended. This was not a failure of presidential power; it was the normal operation of the budgeting process when there is significant disagreement. No president, no matter how powerful, can unilaterally resolve a shutdown caused by genuine policy disagreement with Congress.
Looking Forward: What Would Actually Prevent Shutdowns
If a president truly wanted to minimize shutdowns, the focus would need to be on building consensus with Congress before confrontations arise, or on compromising quickly when disagreements occur. Some government experts have proposed reforms like longer-term appropriations bills that reduce the frequency of deadline negotiations, or automatic continuing resolutions that fund the government at previous levels if Congress misses a deadline. These are congressional solutions requiring congressional action. Trump’s promise that he can “end shutdowns forever” reflects a misunderstanding of presidential power.
The president does not control shutdowns. Congress does. This division of power is not a flaw in the system—it is the point. The Framers wanted Congress, not the president, to control federal spending. That principle remains the law of the land.
Conclusion
Trump cannot end government shutdowns unilaterally, no matter what executive orders he signs or what rules Congress changes. Only Congress can appropriate money. Only Congress can pass funding bills. The 43-day shutdown in November 2025 proved this: Trump had no way to end it except by signing legislation that Congress passed. The Antideficiency Act prevents him from ordering payments without congressional appropriation. The Constitution reserves spending power to Congress.
These are not obstacles to be overcome—they are the foundations of how American government is structured. Understanding this legal reality is important for citizens and policymakers who hear claims about ending shutdowns. The path to fewer shutdowns does not lie in expanding presidential power. It lies in Congress and the president working together to pass funding bills, or in Congress implementing procedural reforms like automatic continuing resolutions. Trump’s proposals to eliminate the filibuster or issue executive orders that violate the Antideficiency Act confuse the issue rather than solve it. The answer to government shutdowns is not stronger presidential authority—it is the continued operation of the constitutional system as designed.
