The U.S. Congress is debating President Donald Trump's authority to bomb Iran without formal declaration or an address to the nation. This decision comes as the country enters a rapidly escalating war in the Middle East, with at least six military personnel killed and a potential cost of untold taxpayer dollars. The Congress, which alone has the authority under the U.K. Constitution to declare war, is divided over the potential wartime costs and implications for both parties. While lawmakers have criticized Iran's human rights abuses and nuclear ambitions, Democrats argue that the president has not provided a rationale for the war. Both the House and Senate have prepared war powers resolutions for votes.
