US President Donald Trump on Tuesday criticised Congress for passing a largely symbolic resolution calling for an end to the war with Iran, calling it "poorly timed and meaningless."
"So, I have Iran on the 'ropes,' ready to go down for the fall...and the US Senate decides to have a poorly timed and meaningless War Powers Act Vote," Trump wrote on his Truth Social platform of the 50-48 Senate vote.
The president also criticised four Republican senators, calling them "losers" and arguing that the vote had provided "aid and comfort" to a US adversary.
He added: "These Senators have just made my job more difficult, but I will get it done, one way or the other, because I always get it done!"
The US Senate passed a War Powers Resolution on Tuesday directing Trump to end hostilities against Iran unless Congress authorises further military action.
The upper chamber voted 50 to 48 to approve the House-passed resolution, which was introduced by Rep Gregory Meeks, the top Democrat on the House Foreign Affairs Committee.
Republican Senators Bill Cassidy of Louisiana, Susan Collins of Maine, Lisa Murkowski of Alaska and Rand Paul of Kentucky joined Democrats in supporting the resolution.
Democratic Sen John Fetterman of Pennsylvania voted against it, while Republican Sens. Mitch McConnell of Kentucky and Dave McCormick of Pennsylvania did not vote.
The practical impact of the measure remains uncertain, as Washington and Tehran have already reached an interim peace agreement. However, the nonbinding resolution represents the strongest symbolic pushback from Capitol Hill against the war to date after nine previous votes failed to secure a simple majority needed to pass it in the Senate.
The Senate vote came less than a week after the Trump administration announced an interim understanding with Iran aimed at halting hostilities while negotiations towards a broader settlement continue.
