The House voted Thursday to demand President Donald Trump seek congressional authorization before continuing military operations against Iran, the second such rebuke the chamber has delivered in the current conflict.
A bloc of House Republicans again crossed the aisle to support the war powers measure, joining Democrats to force the resolution through over White House objections. The precise tally was not immediately confirmed, but the margin tracked the earlier vote.
The move puts fresh pressure on a president who has conducted strikes against Iran without requesting a formal authorization for use of military force from Congress. Democrats and a minority of Republicans have argued the action runs afoul of the 1973 War Powers Resolution.
Republican leadership has largely defended the administration's position, framing congressional action as an interference with the commander-in-chief's authority during active military operations.
The White House has not indicated it will comply with the resolution, which carries political weight but does not carry the force of a veto-proof statute.
The measure moves to the Senate, where Republican leaders have shown little appetite for scheduling a floor vote. A companion resolution is expected to be filed by Senate Democrats in the coming days.
