The U.S. House of Representatives voted Thursday to limit President Donald Trump's authority to strike Iran, a mostly symbolic move Democrats say defends Congress's constitutional powers but Republicans say endangers national security.

The resolution was adopted on a 224-194 vote, as tensions in the Middle East remain high after a U.S. drone strike killed Iranian general Qassem Soleimani. Iran retaliated with missiles striking an Iraqi base used by U.S. troops late Tuesday, without casualties, leaving uncertainty about future hostilities.

With Thursday's resolution, the House is saying that Congress should be consulted before the conflict with Iran escalates. The Senate now can either consider the House-passed measure or move forward with a different version introduced by Sen. Tim Kaine, a Democrat from Virginia.
