Trump Lashes Out at ‘Meaningless’ Senate Rebuke Over Iran War

Senate Passes Resolution Calling for Congressional Authorization on Iran Military Operations

The Senate voted 50-48 on Tuesday to approve a concurrent resolution directing the president to terminate U.S. military involvement in operations against Iran unless Congress grants explicit authorization to continue. The measure, which mirrors a House resolution adopted earlier in the month, received support from four Republican senators—Bill Cassidy of Louisiana, Susan Collins of Maine, Lisa Murkowski of Alaska, and Rand Paul of Kentucky—along with all Democrats except John Fetterman of Pennsylvania. Senators Mitch McConnell of Kentucky and Dave McCormick of Pennsylvania did not vote.

President Donald Trump described the action as poorly timed and said it complicated ongoing diplomatic efforts. In a post on Truth Social, he stated that he would still pursue a negotiated outcome. The administration maintains that a cease-fire effective April 8 ended active hostilities and that further congressional approval is not required. It has also maintained that the 1973 War Powers Resolution is unconstitutional in relevant parts, though it has complied with notification requirements to preserve relations with Congress.

The resolution’s legal effect remains in question. The War Powers Resolution provides that the president must withdraw forces if Congress directs such action by concurrent resolution. However, the Supreme Court’s 1983 decision in INS v. Chadha held that legislative actions requiring the president to take or refrain from specific steps generally must be presented in a bill passed by both chambers and signed into law. Several senators, including Jim Risch of Idaho, stated on the floor that the concurrent resolution would have no operative effect under that precedent. Concurrent resolutions are typically used for internal congressional matters or to express non-binding sentiment and do not carry the force of statute.

House Foreign Affairs Committee ranking member Gregory Meeks, Democrat of New York, who sponsored the House version, said the measure remains binding under the War Powers Resolution and that legal avenues would be explored to secure compliance. Senator Tim Kaine, Democrat of Virginia, said the vote supplied a procedural path for any future withdrawal of forces.

Republicans hold narrow majorities in both chambers. Some members have expressed concern about the duration and expense of the operations. The midterm elections are scheduled for November. Two Republican senators who have previously opposed restrictions on Iran policy were absent, which contributed to the margin.

The Pentagon initially projected costs of roughly $11 billion for the first week of operations. A later estimate from the Center for Strategic and International Studies placed cumulative costs near $40 billion. The administration has requested supplemental appropriations to cover Iran-related expenses. House Minority Leader Hakeem Jeffries, Democrat of New York, criticized further spending on the operations.

The Senate action marks the first time both chambers have approved a concurrent resolution invoking the War Powers Resolution’s termination provision against this set of operations. Debate continues over whether the Chadha ruling renders that mechanism unenforceable and whether separate legislation would be required to impose a statutory restriction. Administration officials have indicated they will continue diplomatic negotiations regardless of the vote’s outcome.
