S. J. Res. 104 would direct "the President to remove the United States Armed Forces from hostilities within or against Iran, unless explicitly authorized by a declaration of war or a specific authorization for use of military force."

On March 4, 2026, Senator Tim Kaine (D-Va.), who introduced S. J. Res. 104 along with Senator Rand Paul (R-Ky.), attempted to get his resolution out of committee and to the Senate floor by making a motion to discharge it. His motion was rejected by a vote of 47 to 53 (Roll Call 46). We have assigned pluses to the yeas because the Constitution delegates the power to declare war to Congress, not the president. Four days earlier, President Donald Trump had transgressed this congressional power when he initiated a war against Iran without first asking Congress for authorization. Paul was the only Republican who voted yea. Yet every senator - regardless of his position on the war - should have voted for this resolution insisting that the president abide by the Constitution.
