The U.S. Senate has agreed to limit President Trump's ability to wage war against Iran.
On Thursday, the Senate voted 55 to 45 in favor of the War Powers Resolution.
Eight Senate Republicans joined the chamber's Democrats to support the legislation.
The law requires President Trump to remove U.S. troops engaged in hostilities against Iran unless Congress declares war, or authorizes the use of military force.
The resolution comes after the U.S. drone killing last month of Iranian military commander Qassem Soleimani in Baghdad, and Tehran's retaliation to that killing, had raised fears of war between the two countries.
"But the Senate just sent a clear shot across the bow. A bipartisan majority of senators don't want the president waging war without congressional approval. That sums up the whole thing."
Some Republican Senators, however, said the move will undermine deterrence measures and leave U.S. troops vulnerable.
House Speaker Nancy Pelosi said she would bring the Senate measures up for a House vote later this month.
But even if it passes the House, Trump is almost certain to veto it.
Congress can override the President's veto, when two-thirds of both the House and Senate agree on it, but that seems unlikely.
