The U.S. Senate is headed towards a vote on President Donald Trump’s decision to embark on a war against Iran. It's an extraordinary test in Congress for a conflict that has rapidly spread across the Middle East with no clear U.S. exit strategy. The legislation is known as a war powers resolution. It gives lawmakers an opportunity to demand congressional approval before any further attacks are carried out. The votes marked a weighty moment for lawmakers. Their decisions on the five-day-old war — which Trump entered without congressional approval — could determine the fates of U.S. military members, countless other lives and the future of the region.
