The U.S. House of Representatives has voted to invoke the War Powers Act, aiming to halt President Trump's military actions in Iran, marking the first congressional success in ending a conflict that has lasted four months and caused significant civilian casualties and global trade disruptions. This vote, led by Democrats and supported by four Republicans, reflects growing opposition within Trump's party due to the war's negative impacts and the lack of a swift resolution. However, the measure is largely symbolic, as President Trump holds veto power, and Republicans maintain a majority in both the House and the Senate, where similar proposals have been previously rejected. The Trump administration contends that a fragile ceasefire in place since April 8 means the U.S. is not technically at war, a claim contested by lawmakers who argue the administration has not provided adequate consultation or transparency regarding its plans for exiting the conflict.
