Why It Matters
Congress is divided over presidential power to wage war without legislative approval, with the House attempting to impose a 60-day limit on military operations in Iran while the Senate rejected the effort. The split comes as escalating conflict with Iran has killed 18 American service members, disrupted global oil supplies, and driven gas prices above $4 per gallon nationwide.
What Happened
The House approved a War Powers Resolution on Thursday with a 214-208 vote, seeking to force the Trump administration to end military operations in Iran within 60 days unless Congress authorizes continued action. Four Republicans broke ranks to support the measure alongside all Democratic members: Representatives Brian Fitzpatrick of Pennsylvania, Thomas Massie of Kentucky, Warren Davidson of Ohio, and Tom Barrett of Michigan.
The Senate rejected the same resolution in a 47-49 vote on Friday. Two senators who had previously indicated support for the measure—Lisa Murkowski of Alaska and Rand Paul of Kentucky—did not vote. Murkowski left Washington on Wednesday for a family emergency in Alaska. Republican Senator Susan Collins of Maine voted in favor, while Democratic Senator John Fetterman of Pennsylvania opposed it.
The clash reflects a fundamental constitutional disagreement. Secretary of State Marco Rubio stated that “the 1973 War Powers Resolution is unconstitutional,” a position the Trump administration has maintained throughout the conflict.
The fighting intensified after Trump reignited military action against Iran earlier this month, rupturing ongoing 60-day ceasefire negotiations between the two nations. The U.S. and Iran have since engaged in near-daily exchanges of rocket fire.
By the Numbers
18 — Total American service members killed in the conflict
4 — U.S. service members killed in incidents on July 17, July 18 at an airbase in Jordan, and July 19 during a controlled detonation of an Iranian drone in Iraq
100 — Troops injured since July 7
96% — Percentage of injured troops who returned to duty
420 — Total injuries since the conflict began February 28
One-fifth — Portion of the world’s petroleum that traveled through the Strait of Hormuz before Iran restricted traffic
$4.09 — Average U.S. gasoline price per gallon as of Thursday
$37.5 billion — Cost of the war to date
$67 billion — Additional funding the administration has requested from Congress
Zoom Out
The War Powers Resolution of 1973 requires presidents to notify Congress within 48 hours of committing armed forces to military action and to withdraw forces within 60 days unless Congress votes to authorize the operation. Presidents from both parties have challenged the law’s constitutionality, arguing it infringes on executive authority under Article II of the Constitution.
Iran’s blockade of the Strait of Hormuz—a critical chokepoint for global energy supplies—has rippled through international markets. Before the conflict escalated, roughly one-fifth of the world’s oil passed through the waterway. The disruption has contributed to elevated energy prices across the United States and abroad, raising economic and political pressure on the administration.
The Senate vote outcome leaves the Trump administration free to continue military operations without a congressionally mandated timeline. The House measure has no force of law following the Senate’s rejection.
What’s Next
Congress faces a choice between reasserting war powers authority through additional legislative action—unlikely given Senate opposition—or allowing the administration to determine the scope and duration of the Iran conflict. The Pentagon continues to manage casualty operations, including dignified transfers of service member remains at Dover Air Force Base in Delaware. Lawmakers will continue weighing pressure from constituents concerned about both military costs and rising energy prices as negotiations with Iran remain stalled.
