The United States Senate on the 4th failed to advance a bill that aimed to require President Trump to obtain Congressional authorization before taking future military action against Iran.
The Senate vote that day was 47 in favor and 53 against, and the bill did not pass.
In speeches before the vote, most Democratic senators criticized the Trump administration's military strikes against Iran.
According to the US Constitution, only Congress can authorize the initiation of war. Several Democrats have spoken out, stating that the Trump administration's military actions against Iran, taken without Congressional authorization, are considered "illegal."
