US Congress votes to keep Trump's authority to use military force against Iran

Both the US Senate and the House of Representatives voted down measures that would have limited President Trump's authority to use military force against Iran. The votes mean Congress will not require the president to seek its approval before taking such action.

The votes came after heightened tensions with Iran. Some lawmakers argued that the president should not have unilateral power to start a war, while others warned that limiting the commander-in-chief's authority could hamper national security.
