The Senate voted on Tuesday to pass a House-passed war powers resolution directing the administration to withdraw U.S. forces from Iran — a congressional rebuke of the administration over the war in Iran — though legally its effects are likely to be largely symbolic.

The resolution passed by a 50-48 vote, with Republican Sens. Rand Paul (R-KY), Lisa Murkowski (R-AK), Susan Collins (R-ME) and Bill Cassidy (R-LA) again voting in favor and Sen. John Fetterman (D-PA) voting against it. Ultimately, GOP absences enabled the resolution to go forward.

But the resolution, now passed by both chambers, came in the form of a concurrent resolution, which is not submitted to the president and, based on past court precedent, is not seen as carrying the force of law — though a House Democratic aide argued to CNN that the measure would be binding.

Rep. Greg Meeks (D-NY), the ranking member of the House Foreign Affairs Committee and lead Democratic sponsor of the war powers resolution, insisted in a statement, “Regardless of what President Trump says, this measure is binding under the War Powers Resolution, and I will explore all legal avenues to ensure the Executive complies with the will of Congress.”

Unlike previous efforts, however, the concurrent resolution did not require other procedural votes by the Senate, allowing Democrats to take advantage of the Republican absences and move directly toward final passage to deliver a message of rebuke to the administration.

The Senate still has other war powers resolutions pending, including one which passed an initial procedural hurdle, but currently lacks the support to pass through an additional procedural vote and final passage with full attendance. That legislation, which comes in a different form as joint resolutions, would be presented to the president if passed and set up a potential veto or other legal fight.

Republicans warned that adopting the resolution would send a further signal to Iran that it does not need to negotiate or make any compromises with the U.S. as part of ongoing talks.
