The U.S. House of Representatives narrowly voted against a resolution aimed at limiting President Trump's military actions against Iran. The vote, held on April 16, ended with 214 in favor and 213 against. The resolution, sponsored by Democrats, sought to require congressional authorization for any further military operations against Iran. This follows the Senate's rejection of the resolution the previous day. Democrats have vowed to continue pushing similar measures until the conflict with Iran is resolved or Congress grants authorization for military action. Under the U.S. Constitution, Congress holds the power to declare war. A 1973 law allows the president to conduct limited military actions without congressional approval only in cases of national emergencies, such as an attack on the United States or an imminent threat.
