The Senate was also expected to vote on War Powers resolution, in largely symbolic move attempting to reign in Trump.Four Republicans in the United States House of Representatives have again joined Democrats in voting to constrain President Donald Trump’s power to wage war against Iran.The resolution passed on Thursday, nearly a week after three US military personnel were killed by an Iranian attack on a base in Jordan, with a 214-208 vote. Senate Minority Leader Chuck Schumer has said Democrats will also force a War Powers vote in the Senate on Thursday.Recommended Stories list of 3 itemslist 1 of 3Why is Iran still able to conduct deadly attacks on US military sites?list 2 of 3US House passes $1.15 trillion military bill expanding Israel cooperationlist 3 of 3US attacks Iran for 12th night as the House approves defence spendingend of listBoth the House and Senate had previously passed a resolution in June that called on Trump to seek congressional approval before launching further attacks. However, because the resolution was passed as a so-called “concurrent resolution”, it was not sent to Trump’s desk.Even if the measure had been passed as a joint resolution, requiring it to be sent to Trump for approval, the president could veto it. Overriding such a veto requires a two-thirds vote in both chambers.Democrats have said the latest resolution sends an important message that lawmakers oppose Trump’s approach to the war, which has re-escalated after a ceasefire broke down in early July.Both the US and Iran have traded 12 days of consecutive attacks, with some analysts warning an even greater US escalation may be on the horizon, as Trump has repeatedly threatened attacks on civilian infrastructure and a possible ground invasion.“This is a vote that requires us to find the strength to do what is right for the American people, and to send the clearest, even stronger message to this president of the United States that the United States Congress, the House of Representatives, is reasserting our authority over war,” Representative Pramila Jayapal said from the House floor on Wednesday.“This war must end,” she said.Under the US Constitution, only Congress can declare war, something it has not done since World War II, although presidents can commit forces in instances of pressing self-defence.Trump has argued that the culmination of Iran’s actions since 1979 represents such an imminent threat, a claim many constitutional law experts have rejected.Under the 1973 War Powers Act, presidents must receive congressional approval within 60 days of committing troops. While the US-Israel war with Iran began on February 28, the Trump administration claimed that hostilities had “terminated” following a temporary pause in fighting reached in April.War powers experts and some members of Congress have said the attempted workaround flouts the law. The administration again notified Congress that fighting had resumed before the most recent round of attacks.In a statement on Thursday, David Janovsky, acting director of The Constitution Project at the Project On Government Oversight (POGO), said the House vote “reaffirmed what people across the country have been saying all along: We want no part in an illegal war”.“Contrary to the administration’s claims, the latest hostilities are not a new war. We’re now months past the constitutional deadline for the administration to end this unauthorised war,” he said.He also noted that the House on Tuesday approved a sprawling $1.15 trillion defence bill that includes tens of billions more in funding for the war. The Senate has not yet voted on the package.“If Congress is serious about bringing an end to this prolonged conflict, it must also refuse the administration’s request to fund it,” he said.
