The Senate has rejected another bid to rein in President Trump’s ability to use further military force against Iran, marking Democrats’ fifth effort to do so since the war began on February 28. On Wednesday, the Senate voted 46 to 51 to defeat the war powers resolution, with Senator Rand Paul the only Republican voting to advance the measure, and Senator John Fetterman the lone Democrat in opposition. Three senators — Republican Chuck Grassley of Iowa, Republican Dave McCormick of Pennsylvania and Democrat Mark Warner of Virginia — did not vote. The resolution was sponsored by Democratic Senator Tammy Baldwin of Wisconsin. Under the War Powers Act, President Trump has until May 1 — 60 days since formally notifying Congress of the U.S.-Israeli war on Iran — to halt all military operations unless lawmakers vote to declare war or authorize the use of force against Iran.
