- Republican Senator Susan Collins joined Democrats in voting against continued hostilities — the first time she crossed party lines on Iran
What Happened
President Donald Trump sent letters on May 1 to House Speaker Mike Johnson and Senate President Pro Tempore Chuck Grassley asserting that the military hostilities with Iran that began on February 28, 2026, had “terminated.” The claim was made explicitly to preempt the expiration of the 60-day clock under the War Powers Resolution of 1973, which requires the president to either obtain congressional authorization for military action or begin withdrawing forces once the threshold is crossed.
“The hostilities that began on February 28, 2026, have terminated,” Trump wrote. He simultaneously acknowledged in the same letter that “the threat posed by Iran to the United States and our Armed Forces remains significant,” and that the conflict may be far from over. The letters were sent as the Senate was about to leave town for a week-long recess without voting on any war authorization measure.
The administration’s legal theory rests on the assertion that the April 7 ceasefire paused the 60-day clock, rendering the statutory deadline inapplicable. Defense Secretary Pete Hegseth had previewed the argument in Senate testimony the day before, telling senators, “We are in a ceasefire right now, which our understanding means the 60-day clock pauses or stops.” Critics from both parties rejected that interpretation.
Senator Susan Collins of Maine, one of the most senior Republicans in the chamber, stated that the 60-day deadline is “not a suggestion, it is a requirement.” Collins voted with Democrats on a war powers resolution — the first time she crossed party lines on the Iran conflict. Other Republican senators including Thom Tillis of North Carolina, John Curtis of Utah, and Lisa Murkowski of Alaska said they expected Congress to eventually vote to authorize the war.
Why It Matters
The War Powers Resolution was passed in 1973 specifically to prevent the executive branch from waging extended military campaigns without congressional input, after presidents used broad interpretations of their commander-in-chief authority to prolong the Vietnam War without a formal declaration. Trump’s argument that a ceasefire effectively pauses the legal clock has no established precedent and has been rejected by constitutional scholars across the political spectrum.
Democratic Senator Richard Blumenthal stated plainly that a blockade — which the U.S. Navy continues to enforce — is itself an act of war. “There’s no pause button in the Constitution, or the War Powers Act. We’re at war. We’ve been at war for 60 days,” Blumenthal said. The distinction matters: the U.S. has been interdicting vessels, seizing tankers, and enforcing a naval cordon around Iranian ports even during the nominal ceasefire period.
The administration’s refusal to seek a formal Authorization for Use of Military Force from Congress has also created a funding gap. No supplemental war appropriations bill has been submitted. Without congressional authorization or a supplemental request, the war is being financed through existing Pentagon appropriations not designed to cover open-ended combat operations, raising legal questions about how funds are being spent.
Rep. Adam Smith of Washington, the top Democrat on the House Armed Services Committee, captured the broader governance concern with a grim observation: “Is the expectation that the Trump administration is going to follow the law? I do not have that expectation.” The statement reflects a view among many Democrats — and some Republicans — that the administration has systematically avoided the institutional checks that govern the use of military force.
Economic and Global Context
The War Powers clock dispute has unfolded against an energy crisis of historic proportions. The Strait of Hormuz, through which a fifth of the world’s oil normally transits, has been largely closed since late February due to the conflict. Iran closed the strait, and the U.S. subsequently imposed its own blockade on Iranian ports. Even if a ceasefire holds, analysts warn that energy prices could remain elevated for months as the shipping backlog is cleared and Iranian mines are removed from navigation lanes.
The CBO and independent analysts have warned that the proposed $200 billion war supplemental — which the administration has been considering but has not formally requested — would substantially add to a national debt that already exceeds $39 trillion. The One Big Beautiful Bill Act, signed in July 2025, added an estimated $3.4 trillion to the debt over ten years. Piling hundreds of billions in war costs on top of that trajectory is drawing concern even from fiscal hawks in the Republican Party.
Internationally, the administration’s circumvention of Congress has fueled arguments among allies that the United States is operating outside established norms. The United Nations Secretary-General has previously raised concerns about the legality of U.S. operations in the region, and the pattern of unilateral executive action — from Venezuela to Iran — has strained relationships with European partners who have publicly called for greater adherence to international frameworks.
Implications
The administration is unlikely to seek a formal AUMF unless it faces imminent legislative defeat, given that Republican leaders have so far blocked Democratic war powers resolutions. But the political dynamics are shifting. Several Republican senators who have expressed discomfort — including Collins, Tillis, Curtis, and Murkowski — represent a potential coalition that, if expanded, could force the administration’s hand.
Senator John Curtis of Utah has said he will not support continued funding for the war until Congress votes to authorize it, a position that has significant implications for the supplemental spending request that is expected to arrive on Capitol Hill in coming weeks.
For American voters, the dispute is ultimately about democratic accountability. An undeclared war that has killed 15 Americans, costs tens of billions in direct expenses, and has driven gas prices up more than 50 percent is proceeding without any formal legislative mandate — and the White House’s legal argument for avoiding one has been rejected by members of the president’s own party.
