The Republican-led Senate on Wednesday rejected the latest Democratic attempt to halt President Donald Trump's war in Iran, turning aside a resolution that would require the US to withdraw forces from the conflict until Congress authorizes further action. The 47-52 vote was the fourth time this year that the Senate has voted to cede its war powers to the president in a conflict that Democrats say is illegal and unjustified.

Republicans say they will keep faith in Trump's wartime leadership, for now, citing Iran's nuclear capabilities and the high stakes of withdrawal. But GOP lawmakers are also anxious for the conflict to end - and they may not defer to the executive branch indefinitely. Some Republicans have already made clear that they are eyeing future votes that could become an important test for the president if the war drags on.
