US Senate Rejects War‑Powers Limit as Public Opposition to Iran War Swells

US Senate war powers resolution Iran conflict public opinion poll Donald Trump

On July 30 2026 the United States Senate voted 49‑50 to defeat a war‑powers resolution that would have required President Donald Trump to withdraw U.S. forces from Iran absent an explicit congressional authorization. The measure was supported by three Republican senators—Susan Collins, Lisa Murkowski and Rand Paul—who broke with most of their party, while Democratic senator John Fetterman voted with Republicans, delivering the defeat. Senate Minority Leader Mitch McConnell was absent from the roll call.

The vote comes amid a war that began on February 28, 2026 and has resulted in the deaths of 18 U.S. service members. Public opinion has turned sharply against the conflict: an AP‑NORC poll conducted July 23‑27 found that roughly 64 % of American adults consider the Iran war “not worth fighting.” Approval of Trump’s handling of the war fell to 28 %, and Republican approval of his policy dropped from 71 % in June to 61 % in July. The growing domestic backlash adds pressure on Congress as the conflict continues.
