US Senate blocks war powers resolution seeking to curb Trump’s Iran campaign
Supporters argued that Trump overstepped constitutional authority by launching military action alongside Israel without approval from Congress
WASHINGTON (MNTV) — The U.S. Senate has rejected a resolution aimed at limiting President Donald Trump’s military campaign against Iran, dealing a blow to lawmakers seeking to reassert congressional authority over war powers.
The measure failed 47–52 in a procedural vote, largely along party lines.
A similar resolution is expected in the House of Representatives but faces uncertain prospects.
Supporters argued that Trump overstepped his constitutional authority by launching military action alongside Israel without explicit approval from Congress.
Under Article II of the U.S. Constitution, presidents may act in self-defense against imminent threats, while Congress retains the sole authority to declare war.
Senator Tim Kaine, a leading sponsor, said the administration had not presented evidence — even in classified briefings — that Iran posed an immediate threat to the United States.
He rejected claims that the strikes were limited or isolated, warning they risked drawing U.S. forces into a broader conflict.
Republicans, however, rallied behind the president. Senator James Risch argued that the Constitution empowers the commander-in-chief to defend the country and cited Iran’s missile development and nuclear activities as justification for military action.
Since launching the offensive on February 28, the administration has offered shifting explanations, including allegations that Iran was rebuilding its nuclear program and developing long-range missiles. Diplomatic talks that had been underway prior to the escalation have since collapsed.
Even if passed, the resolution would likely have faced a presidential veto, requiring a two-thirds majority in both chambers to override.
Advocacy groups said the vote still forces lawmakers to take a public position on executive war powers. As the conflict with Iran deepens, the debate in Washington underscores mounting questions over the scope and duration of U.S. military involvement.
