Reason: “In addition to violating the Constitution, the air strikes also violate the War Powers Act. Section 3 of that legislation requires that ‘the President in every possible instance shall consult with Congress before introducing United States Armed Forces into hostilities or into situations where imminent involvement in hostilities is clearly indicated by the circumstances.'”
“There was no such advance consultation here, even though it was obviously ‘possible’ to do it (US strikes against Iran have been under consideration since Israel began its air campaign on June 13, if not before).”
