As the U.S.-Israel air war against Iran continues, the Senate and House are set to vote this week on war powers resolutions that would aim to cut the U.S. operations short.

The resolutions, led by Sens. Tim Kaine (D-VA) and Rand Paul (R-KY) and Reps. Ro Khanna (D-CA) and Thomas Massie (R-KY), respectively, were originally introduced before the war began, in an effort to block military action and signal dissatisfaction with the then-looming war.

Now, the resolutions, if passed, would force the administration to end the nascent war, withdraw forces and cease operations against the Iranian regime.

It’s almost certain that the resolution will not pass the Senate; the House vote may be closer but it is also not likely to pass. And even if the resolutions were to pass, they would not have the two-thirds support necessary to overcome an inevitable presidential veto.

But the resolution will be an opportunity for Democrats — and a small number of Republicans — to go on record demonstrating their opposition to the war and dissatisfaction with the administration’s approach.

Democrats, even lawmakers like Sen. Jacky Rosen (D-NV) who are relatively hawkish on Iran and have offered some positive feedback about the ongoing operations, are expected to  mostly vote for the war powers resolution.

They have cited concerns about the administration’s failure to brief Congress at large about its plans before launching the war, its decision not to seek congressional authorization for the operations and what they say is the administration’s failure to make the case for war to the American public.

Lawmakers are reportedly set to receive classified briefings on the war on Tuesday from Cabinet and other senior administration officials.

A small number of Democrats will likely vote against the resolutions, such as Sen. John Fetterman (D-PA), an outspoken supporter of the war against Iran, and Rep. Greg Landsman (D-OH), who backed limited operations against Iran and said yesterday he would oppose the resolution.

Two other Democrats, Reps. Josh Gottheimer (D-NJ) and Jared Moskowitz (D-FL), had said before the war started that they would oppose the war powers resolutions, but haven’t specified their plans now that active combat operations are underway.

The key difference between the text of the Senate and House resolutions is language in the Senate version specifically permitting the U.S. to continue intelligence sharing with and providing military aid for Israel and other allies. The House bill does not contain any such language, a potential issue for some supporters of Israel.

Most Republicans, with the exception of some isolationist-leaning lawmakers like Paul, Massie and Rep. Warren Davidson (R-OH), have been offering full-throated support for the Trump administration’s actions and are likely to vote against the war powers resolutions.

Kaine said he expects the Senate vote will happen on Tuesday or Wednesday. The House isn’t set to reconvene until Wednesday, with a vote likely set for Wednesday or Thursday.
