The Republican-majority US Senate backed legislation on Tuesday to stop military action against Iran, reflecting the growing unpopularity of the war as peace negotiations continue.
The Senate voted 50-48 in favour of the resolution, which passed the House of Representatives in early June.
Polling suggests that only one in four Americans believe that the Iran war is worth the cost to the US, affecting Trump’s popularity, which has fallen to record low levels to match the worst recorded in his second term.
