Senate Rejects Democrats' Fifth Bid to Limit Trump's Iran War Powers

In the early hours of Thursday morning Senate Republicans pushed through a budget resolution that unlocks billions of dollars for Immigration and Customs Enforcement and Customs and Border Protection while simultaneously blocking Democratic attempts to restrain President Donald Trump’s expanding military conflict with Iran. The twin votes illustrated the GOP’s determination to advance Trump’s domestic enforcement agenda and foreign policy ambitions with minimal compromise even as the Iran war entered its eighth week and domestic costs continued to mount.

The budget resolution passed at roughly 3:30 a.m. by a 50-48 margin after an all-night “vote-a-rama” filled with procedural maneuvers. Only two Republicans Senators Rand Paul of Kentucky and Lisa Murkowski of Alaska joined every Democrat in opposition. Senators Chuck Grassley Republican of Iowa and Mark Warner Democrat of Virginia did not cast votes. The measure now heads to the House where its fate is uncertain but its adoption in the Senate effectively green-lights the use of budget reconciliation to lock in multi-year funding for ICE and CBP without needing Democratic support.

That procedural path is no accident. Republicans turned to reconciliation after Democrats refused to support standalone immigration funding bills without accompanying policy changes. The resolution sets up appropriations that according to GOP leadership will sustain heightened enforcement through the remainder of Trump’s term. Senate Majority Whip John Barrasso of Wyoming framed the move as a necessary response to what he called “reckless Democrat hostage-taking.” Yet the late-night process sidelined repeated Democratic efforts to force votes on lowering out-of-pocket healthcare costs the very issue Senate Minority Leader Chuck Schumer argued Americans actually care about.

“Instead of pumping hundreds of billions of dollars into ICE and Border Patrol Republicans should be working with Democrats to lower out-of-pocket costs,” Schumer said during the debate. Democrats had offered multiple amendments on healthcare only to see them set aside in favor of the immigration funding blueprint.

The same marathon session featured another revealing vote. For the fifth time since early March Republicans defeated a Democratic war powers resolution aimed at forcing Trump to withdraw U.S. forces from hostilities with Iran unless Congress explicitly authorizes continued fighting. The 51-46 vote fell largely along party lines with Paul once again breaking ranks to support the Democratic measure and Senator John Fetterman of Pennsylvania crossing over to back the GOP. Senator Tammy Baldwin the lead sponsor from Wisconsin condemned the war as “unnecessary illegal and unwise.”

“This entire war has been unnecessary illegal and unwise,” Baldwin said on the Senate floor. “The president said the war would be over in a matter of days. We are coming up on the two-month mark with no real end in sight. And over the course of 50-plus days we have seen nothing short of a disaster.”

Senator Tammy Duckworth an Illinois Democrat and combat veteran vowed Democrats would keep pressing the issue. “It’s infuriating that Senate Republicans keep shirking their oaths and giving Donald Trump the green light to plunge our nation even deeper into his war of choice further endangering our troops abroad and surging prices at home,” she said in a statement. The reference to rising costs at home echoed Schumer’s critique that the Republican priority list places border agencies and foreign conflicts ahead of American families struggling with everyday expenses.

New York Times reporter Maggie Haberman who has covered Trump for years told CNN that the president is showing clear signs of frustration with a war he expected to conclude rapidly. “He’s clearly frustrated. He’s voicing that almost every day,” Haberman said. “My sense is the president would like to just be done with this and he has other things he’d like to focus on. But wars are intractable.” She noted a gap between Trump’s public desire to move on and the positions of Iranian and Pakistani interlocutors. Behind-the-scenes efforts involving Jared Kushner Steve Witkoff and Vice President JD Vance have continued through intermediaries but no breakthrough has been announced despite a fragile cease-fire now in place.

The convergence of these votes in a single overnight session underscored a coherent Republican strategy. By using reconciliation Republicans can deliver on Trump’s promise of a well-funded deportation and border apparatus without Democratic votes. At the same time the repeated rejection of war powers measures effectively hands the president wide latitude to prosecute a conflict that senior Democrats describe as unplanned and open-ended. Critics argue the approach reveals a willingness to expand both domestic enforcement infrastructure and overseas military commitments while brushing aside concerns about fiscal priorities and congressional war-making authority.

What happens next is unclear. The House must still act on the budget resolution and any final appropriations package would require additional votes in both chambers. Negotiations to end the Iran conflict remain delicate. Yet the early-morning results left little doubt about Republican intentions in the current Congress: fund the agencies tasked with carrying out Trump’s immigration vision at scale and resist any legislative leash on his military decisions abroad. Democrats who have now lost five consecutive votes on war powers signaled they intend to keep forcing the issue highlighting what they see as both a policy failure and a constitutional abdication.

The overnight votes arrived as reports of the human and financial toll of the Iran conflict continued to surface. With the war now stretching into its second month and Trump himself expressing impatience the Senate’s refusal to reassert its role leaves the trajectory of American involvement largely in the president’s hands. At the same time the immigration funding pathway sets the stage for an expanded enforcement apparatus that will likely define domestic policy debates for the remainder of the administration.
