Both the House and Senate have drafted resolutions requiring congressional approval for further military action in Iran. NPR reports votes are expected Wednesday or Thursday.
Speaker Mike Johnson called limiting the president's authority "dangerous." Republican senators are expected to block passage. Senator Rand Paul and a small caucus of libertarian-aligned Republicans may cross party lines, but their numbers are insufficient for a majority in either chamber. Democrats are unified in support. Even if both chambers passed the measures — an outcome no serious whip count supports — a presidential veto would follow. Overriding it requires two-thirds majorities that do not exist.
The vote's purpose is therefore documentary, not operational. It creates a formal record that Congress did not authorise the campaign — a record that acquires weight because the campaign's legal basis is already contested from within the national security establishment. Secretary of State Marco Rubio told congressional leaders after a classified briefing that the US launched pre-emptive strikes because it knew Israel was going to attack Iran and anticipated retaliation against American forces. Senator Mark Warner, vice-chairman of the Senate Intelligence Committee, stated publicly that he had seen "no intelligence" supporting the administration's imminent-threat claim. Rubio's formulation — that the US struck first to mitigate blowback from an ally's operation — describes a strategic choice, not self-defence as defined by the War Powers Resolution.
The War Powers Resolution was written for precisely this scenario: a president committing forces to sustained combat abroad without congressional authorisation. That it cannot function here — that the votes will fail along party lines regardless of the legal merits — places the conflict in a category the framework's 1973 authors anticipated but could not solve. The president has sixty days of unilateral authority under the Resolution. The campaign is on day four. Congress, the UN Security Council (blocked by Russia and China), and regional mediators are all simultaneously unable to act. The institutions designed to constrain or end armed conflicts are either paralysed, powerless, or — in the case of the Assembly of Experts headquarters in Tehran — literally under fire. The conflict is operating in an institutional vacuum, with no mechanism capable of producing a binding constraint on any party.
