Senate War Powers Vote Fails — Joint Chiefs Orders Deeper Strikes the Same Day

The evening briefing on a failed war powers vote that leaves Congress without a check on the Iran operation, a U.S. submarine confirmed in the Indian Ocean kill, Iran's arsenal showing signs of depletion, and NATO intercepting its first missile of the conflict.

The U.S. Senate voted 47-53 Wednesday to reject a war powers resolution that would have required President Trump to seek congressional approval to continue military operations against Iran. The measure, brought by Sen. Tim Kaine (D-VA) and Sen. Rand Paul (R-KY), fell short of the 50-vote threshold needed to advance. Paul was the only Republican to support it. Sen. John Fetterman (D-PA) was the only Democrat to vote against it, siding with Republicans to block the measure. Even if the resolution had passed the Senate, it faced a near-certain presidential veto and the two-thirds override threshold that Democrats cannot reach alone.

The vote came on the same day Chairman of the Joint Chiefs Gen. Dan Caine announced the U.S. would begin “striking progressively deeper” into Iran. The administration now has no active congressional check on the scope, duration, or geographic expansion of the operation. Trump’s War Powers notification — submitted two days late and omitting regime change as a stated objective — remains the only formal accounting Congress has received. The Senate’s decision to shield the president closes, for now, the most direct institutional mechanism for demanding answers.

U.S. Submarine Confirmed as the Weapon That Sank IRIS Dena

Defense Secretary Pete Hegseth confirmed Wednesday that a U.S. submarine torpedoed the Iranian Navy frigate IRIS Dena in international waters off Sri Lanka — the vessel that went down early this morning. Sri Lanka's navy said it recovered several bodies; the full casualty toll remains unclear with over 100 personnel still unaccounted for. Gen. Caine said the U.S. and Israeli strikes have "effectively neutralized" Iran's naval capacity as of Day Five. White House Press Secretary Karoline Leavitt said the U.S. aims to completely eliminate Iran's navy, claiming more than 20 Iranian ships have now been destroyed, including the country's top submarine.

NATO Intercepts Iranian Missile Headed Toward Turkey

NATO air defense systems shot down an Iranian missile traveling toward Turkish airspace Wednesday — the first time NATO forces have intercepted an Iranian missile targeting a member country since the conflict began. The intercept raises the conflict's stakes significantly: any missile that crosses into Turkey's territory constitutes an attack on a NATO ally, triggering potential Article 5 obligations. Iran's Foreign Minister has maintained that Tehran's strikes are directed at U.S. military assets, not neighboring states. The missile's intended target has not been confirmed. Iran's overall missile and drone launch volume has dropped sharply — 86% and 73% respectively compared to Day One, according to Gen. Caine, suggesting meaningful depletion of the country's arsenal.

Israel Vows to Kill Iran's Next Supreme Leader — Mourning Ceremony for Khamenei Cancelled

Israeli officials stated Wednesday that whoever Iran selects as Khamenei's successor will be "an unequivocal target for elimination." The statement came as Iran cancelled the mourning ceremony for Khamenei that had been scheduled to begin Wednesday evening — a visible sign of the regime's struggle to project stability. Senior Iranian officials have been meeting virtually to select a successor, with Khamenei's son Mojtaba among a small group of clerics under consideration. Trump, meanwhile, said publicly that he believes "someone from within" the current Iranian government may be the best path to post-war leadership — a statement that contradicts Leavitt's framing of total regime elimination and adds another layer to the administration's already competing narratives on war objectives.

What to Watch For

WHAT TO WATCH TOMORROW

Bushehr nuclear plant — Russia’s warning about the active nuclear facility remains unresolved. Any strike on or near Bushehr forces an IAEA response and changes the international calculus overnight.

House War Powers vote — The House is scheduled to take up a similar war powers resolution Thursday. Watch the Republican count — it tells you how much political cover the party is willing to provide, or not.

Bottom Line

The Senate declined to check the president's war powers on the same day the Joint Chiefs announced the strikes would go deeper. Congress now has no active mechanism to demand answers on scope, duration, or objectives. The War Powers notification remains the only formal accounting — and it still doesn't mention regime change.
