A group of Republican senators is drafting plans for a potential officially authorise a war against Iran if US strikes resume, according to a report by Semafor.
The effort continues behind closed doors as lawmakers anticipate a possible return to hostilities following comments by US President Donald Trump that the initial phase of the conflict has ended.
Under the War Powers Act, Congress can fast-track consideration of a military authorisation if it is introduced within the early phase of renewed fighting, potentially allowing for a rapid vote in the Senate.
Advisers are also assessing the voting threshold required to pass the measure, with some Republicans arguing it may clear the chamber with a simple majority rather than the higher 60-vote hurdle.
The proposed authorisation is expected to restrict the deployment of ground forces and limit the duration of any military engagement.
