The Senate passed a resolution that would limit the authority of President Trump to confront Iran in a war.
It would require President Trump to obtain permission from Congress before ordering military action against Iran.
A bipartisan vote of included eight Republicans who voted in favor of the legislation.
Those Republicans include Senators Susan Collins (R-ME), Mike Lee (R-UT), Rand Paul (R-KY), Jerry Moran (R-KS), Lisa Murkowski (R-AL), Todd C. Young (R-IN), Lamar Alexander (R-TN.) and Bill Cassidy (R-LA).
President Trump is expected to veto the measure if it reaches his desk.
According to CNN, Virginia Democratic Sen. Tim Kaine, who introduced the resolution said: “We should not be at war with Iran unless Congress votes to authorize such a war.”
“While the President does and must always have the ability to defend the United States from imminent attack, the executive power to initiate war stops there,” Kaine added.
“An offensive war requires a congressional debate and vote. This should not be a controversial proposition,” Kaine concluded.
