Senate Votes 50-48 to Rein In Trump's Iran War, a First for Congress

The United States Senate voted on Tuesday to order President Donald Trump to stop the war against Iran unless Congress signs off on it, the first time a war powers resolution has cleared both chambers and a rare institutional check on a sitting commander in chief.

The 50-48 vote adopted a measure the House had already passed on June 3 by 215 to 208. Because it is a concurrent resolution, it never reaches the president's desk and carries no force of law. The weight is in the precedent. For the first time, both houses of Congress have formally told a president to halt a war he launched on his own authority.

Four Republicans crossed the aisle to back it: Bill Cassidy of Louisiana, Lisa Murkowski of Alaska, Susan Collins of Maine and Rand Paul of Kentucky. Two more, Mitch McConnell and Dave McCormick, did not vote, and their absence helped tip the count. Pennsylvania Democrat John Fetterman was the only member of his party to vote no. The arithmetic was narrow, but for a chamber Trump's party controls, the direction was the news.

Senate Minority Leader Chuck Schumer, who has forced these votes repeatedly, framed the conflict as a self-inflicted wound.

"For years, Trump promised to put maximum pressure on Iran, but he ended up delivering maximum confusion, maximum chaos, maximum cost to the American people with his disastrous war."

The vote lands in the middle of a fragile pause. Trump joined Israel in striking Iran on February 28, touching off a region-wide war, and the two sides signed a memorandum of understanding on June 17 that started a 60-day clock toward a broader deal. Negotiators are still meeting in Switzerland, even as Israeli fire in Lebanon has tested the terms. Daybreak Wire has tracked the diplomacy in its coverage of the 60-day roadmap agreed in Switzerland and the sanctions waiver tied to reopening Hormuz.

Republicans who opposed the resolution argued it would weaken the US hand at the table. Idaho's James Risch warned that Tehran would read it as a green light to walk. "If this passes, the Iranians are going to simply stand up and walk away from negotiations," he told the chamber, calling the measure useless because "the president isn't going to pay any attention to it."

That may be the point most worth sitting with. The resolution does not bind Trump, and the White House has shown no sign of treating it as anything but noise. What it does is put a recorded number on congressional unease, at a moment when the bills are coming due. The Pentagon is seeking roughly $80 billion in supplemental funding largely tied to the war, which it first estimated cost $11.3 billion in its opening week; outside experts put the full price near $100 billion. Republicans have balked in particular at a $300 billion fund to help Iran rebuild. "I believe President Trump is getting very poor advice on Iran," Senator Ted Cruz said last week.

Public patience is thin. A Reuters/Ipsos poll released Tuesday found that just 24 percent of Americans felt the war had been worth the cost, with prices for oil, gas and fertiliser still elevated months after the Strait of Hormuz seized up.

Virginia's Tim Kaine, who has chased a measure like this for years, kept his argument constitutional. "The most solemn power for Congress is Congress has the power to declare war, not the president," he said, recalling that the country's founders vested that decision in the legislature precisely because the stakes were too large for one person. Asked last week whether the war had taught him any limits on his own authority, Trump answered: "There are no limits." The Senate, with four of his own senators in tow, spent Tuesday afternoon insisting otherwise. Whether anyone at the other end of Pennsylvania Avenue is listening is a different question, and one the tenth failed-then-passed attempt leaves wide open.
