The US Senate is set to vote on a war power resolution aimed at limiting President Donald Trump’s ability to order further military action in Iran.
The measure would require the withdrawal of US forces from the conflict unless Congress approves the operation. But previous efforts have failed, and it is unclear how much its success would change the war.
Democrats argue that Trump sidelined Congress and has offered shifting reasons for the war. Most Republicans say they will block the resolution, but may change their stance if the war expands.
The vote comes five days after the US and Israel began striking Iran. Iran has responded by launching attacks on Israel and US-allied states in the Gulf.
Since then, some lawmakers have been on edge, waiting to see what role, if any, they will play in the ongoing attacks.
“Every senator will have to go on the record to declare whether it is in our best interest to send our sons and daughters into conflict against Iran,” said Senator Tim Kaine, a Virginia Democrat who sponsored the legislation.
“I pray that my colleagues will vote to end this dangerous and unnecessary war that has already resulted in the loss of six service members and injured others.”
