Republicans had previously been able to muster the votes to reject those proposals, but Louisiana Senator Bill Cassidy \u2014 fresh off a primary election loss in which Trump endorsed his opponent \u2014 switched sides.<\/p>\n<p>The 50-47 vote tally showed that a small but growing number of Republicans are willing to challenge Trump on the Iran war, even though the effort may not advance much further. Three Republicans were absent Tuesday and their votes would be enough to defeat the measure, if they maintain their stance on the war.<\/p>\n<p>Still, the vote showed how Republicans are increasingly uneasy with a conflict that shows no signs of ending, is locked in a fragile ceasefire, and is causing rising gas prices in the US.<\/p>\n<p>\u201cRepublicans are starting to crack, and momentum is building to check him,\u201d Senate Democratic leader Chuck Schumer said in a statement after the vote. \u201cWe are not letting up.\u201d<\/p>\n<p>\n\t\t\tGet The Times of Israel&#8217;s Daily Edition<br \/>\n\t\t\tby email and never miss our top stories\n\t\t<\/p>\n<p>\t\t\t\tBy signing up, you agree to the <a href=\"https:\/\/www.timesofisrael.com\/terms\" rel=\"nofollow noopener\" target=\"_blank\">terms<\/a><\/p>\n<p>Republican Senators Rand Paul of Kentucky, Susan Collins of Maine and Lisa Murkowski of Alaska had all previously voted for similar war powers resolutions and did so again Tuesday. Cassidy supported the legislation for the first time, while Senator John Fetterman of Pennsylvania was again the only Democrat to vote against it.<\/p>\n<p>\t<a href=\"https:\/\/static-cdn.toi-media.com\/www\/uploads\/2026\/05\/AP26137104357748.jpg\" rel=\"nofollow noopener\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-3827128\" src=\"https:\/\/www.europesays.com\/iran\/wp-content\/uploads\/2026\/05\/AP26137104357748-640x400.jpg\" alt=\"\" width=\"600\" height=\"375\"\/><\/a><br \/>\n\t\tUS Senator Bill Cassidy speaks to supporters during an election night watch party, May 16, 2026, in Baton Rouge, Louisiana. (AP Photo\/Gerald Herbert)<\/p>\n<p>After his primary election loss last week, Cassidy returned to Washington defiant. He said he was proud of his work to uphold the Constitution and would carefully consider how he would vote on several priorities of the Trump administration going forward.<\/p>\n<p>Trump\u2019s grip on the Senate Republican Conference is potentially slipping after Cassidy\u2019s primary loss, as well as the president\u2019s decision Tuesday to endorse Republican Senator John Cornyn\u2019s primary opponent.<\/p>\n<p>\u201cWhile I support the administration\u2019s efforts to dismantle Iran\u2019s nuclear program, the White House and Pentagon have left Congress in the dark on Operation Epic Fury,\u201d Cassidy said on social media.<\/p>\n<p>\u201cUntil the administration provides clarity, no congressional authorization or extension can be justified.\u201d<\/p>\n<p>House will also vote on war powers<\/p>\n<p>Across the Capitol, the House is expected to vote on a similar war powers resolution Wednesday, and Democrats are bullish about their chances of passing it. Another war powers resolution barely failed in the House last week, the vote ending in a tie.<\/p>\n<p>Even if Congress eventually passes legislation to compel Trump to withdraw from the conflict, it\u2019s not clear that he would comply.<\/p>\n<p>To circumvent requirements of the War Powers Resolution of 1973, the White House has claimed that it has technically ceased \u201chostilities\u201d with Iran because there is a ceasefire. However, the administration has also said it rejects the 1973 law as unconstitutional.<\/p>\n<p>\t<a href=\"https:\/\/static-cdn.toi-media.com\/www\/uploads\/2026\/05\/AP26098040534414.jpg\" rel=\"nofollow noopener\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-3826010\" src=\"https:\/\/www.europesays.com\/iran\/wp-content\/uploads\/2026\/05\/AP26098040534414-640x400.jpg\" alt=\"\" width=\"600\" height=\"375\"\/><\/a><br \/>\n\t\tActivists protest against the war in Iran at Lafayette Park near the White House in Washington, April 7, 2026.

The administration may have to go into more detail about that, Rounds said.<\/p>\n<p>The War Powers Resolution of 1973 \u201cdoes provide an avenue for that discussion and debate to occur,\u201d Rounds said.<\/p>\n<p>He said he believes it\u2019s not the right time to do that, and he would rather \u201cstand strong with the president\u201d at this point. \u201cBut I think a number of our members maybe just feel like it\u2019s time to have the debate.\u201d<\/p>\n<p>Earlier this year, Republican senators voted to advance a war powers resolution on the conflict with Venezuela and compelled the Trump administration to make its case to Congress for the military campaign.<\/p>\n<p>A handful of GOP senators forced a final vote on legislation to withdraw from the conflict. Two of the Republicans \u2014 Senators Todd Young of Indiana and Josh Hawley of Missouri \u2014 ultimately flipped after Secretary of State Marco Rubio agreed to a public hearing about the administration\u2019s Venezuela strategy.<\/p>\n<p>&#13;<br \/>\n\t\t\t\tWhich gorgeous bird do you prefer?\t\t\t<\/p>\n<p>\t\t\t\t\t\t\t\t\t<img width=\"200\" height=\"200\" src=\"https:\/\/www.europesays.com\/iran\/wp-content\/uploads\/2026\/05\/Untitled-design-3-200x200.png\" class=\"attachment-square size-square wp-post-image\" alt=\"\" decoding=\"async\" loading=\"lazy\" title=\"\"\/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/p>\n<p>THIS MONTH ONLY: Join our reader support group for as little as $6\/month and receive an exclusive tote bag featuring one of Israel\u2019s native birds.<\/p>\n<p>Choose between the\u00a0Duchifat (orange), Israel&#8217;s national bird, or the Shaldag (blue), a beloved symbol of the Israeli landscape.\u00a0<\/p>\n<p>As a member of the Times of Israel Community,\u00a0you&#8217;ll also enjoy:<\/p>\n<p>&#13;<br \/>\nAn ad-free experience of our site and podcasts.&#13;<br \/>\nExclusive access to award-winning films via DocuNation.&#13;<br \/>\nWeekly letters from founding editor David Horovitz.&#13;<\/p>\n<p>\t\t\t<a href=\"https:\/\/crm.timesofisrael.com\/sign-up?utm_source=article&amp;utm_medium=module&amp;utm_campaign=tote_bags&amp;utm_term=both&amp;utm_source=website&amp;utm_medium=article_end&amp;utm_content=BDFCFF\" class=\"crm-post-module__btn crm-post-module__btn-desktop\" rel=\"nofollow noopener\" target=\"_blank\">&#13;<br \/>\n\t\t\t\tJoin ToI Community &amp; claim my bag\t\t\t<\/a><\/p>\n<p>\t\t\t<a href=\"https:\/\/crm.timesofisrael.com\/sign-up?utm_source=article&amp;utm_medium=module&amp;utm_campaign=tote_bags&amp;utm_term=both&amp;utm_source=website&amp;utm_medium=article_end&amp;utm_content=BDFCFF\" class=\"crm-post-module__btn crm-post-module__btn-mobile\" rel=\"nofollow noopener\" target=\"_blank\">&#13;<br \/>\n\t\t\t\tCLAIM YOUR BAG\t\t\t<\/a><\/p>\n<p>\t\t\t<a class=\"crm_under_btn_link\" target=\"_blank\" href=\"https:\/\/crm.timesofisrael.com\/sign-in?RedirectTo=https%3A%2F%2Fwww.timesofisrael.com%2Fus-senate-advances-measure-curbing-trumps-iran-war-powers-nearly-along-party-lines%2F\" rel=\"nofollow noopener\">Already a member?
