The Senate passed the Kaine-Lee war powers resolution 58-42 on Friday afternoon, sending to the House a measure that would require congressional authorization for any renewed U.S. hostilities against Iran and handing the Trump administration its widest bipartisan rebuke since the April 15 ceasefire took effect.

Seven Republicans joined every Democrat and the chamber’s two independents to clear the resolution, two more GOP defections than leadership had projected at the start of the week. The final tally included Sens. Rand Paul of Kentucky, Mike Lee of Utah, Susan Collins of Maine, Lisa Murkowski of Alaska, Todd Young of Indiana, Rand Paul’s longtime ally Sen. Mike Braun of Indiana — who reversed a Thursday-night signal that he would vote no — and Sen. Jerry Moran of Kansas, whose late switch surprised both whips and triggered a brief recess on the floor while leadership conferred.

“The Constitution is not a museum piece,” Sen. Tim Kaine of Virginia, the lead co-sponsor, said in remarks on the floor moments before the vote. “Today, by a margin no one expected when we filed this resolution a week ago, the Senate of the United States has said that the question of war belongs to the people’s branch.”

Sen. Lee, the lead Republican co-sponsor, was sharper. “Three hundred and fifty-eight Americans came home in flag-draped coffins this spring,” he said. “Not one of them died because the Senate was asked. That is the wound this resolution begins to close.”

Majority Leader John Thune did not whip against the measure in its final hours, according to two Senate Republican aides granted anonymity to describe leadership posture, instead instructing members to “vote their conscience and their state.” Thune himself voted no. In a brief statement after the vote, he called the resolution “a symbolic exercise on a war that ended two weeks ago” but said the Senate “did its constitutional work openly, and that is not nothing.”

The vote came roughly three hours after the same chamber, by a 71-29 margin, agreed to begin floor debate on the administration’s $89.4 billion war supplemental — a request that has split House Republicans more sharply than the war powers question and now faces an uncertain path on the other side of the Capitol. Senate Appropriations Chair Susan Collins, who managed the morning’s procedural vote, told reporters she expected substantive amendments throughout next week and a final Senate passage vote “no later than May 8.”

The House response was immediate and divided. Speaker Mike Johnson, in a written statement issued at 2:48 p.m., said the war powers resolution “will receive the consideration the rules of the House provide and not a minute more.” Johnson declined to commit to a floor vote before the Memorial Day recess, a posture that several rank-and-file Republicans said in interviews Friday afternoon was likely to collapse under the weight of the seven GOP Senate votes.

“You cannot let a resolution that got 58 votes in the Senate, including seven Republicans, sit on the speaker’s desk for three weeks,” said Rep. Brian Fitzpatrick of Pennsylvania, who has led a 15-member House Republican bloc demanding a standalone war powers vote attached to the supplemental. “That is not a tenable position politically and it is not a tenable position institutionally.”

House Minority Leader Hakeem Jeffries said Democrats would file a discharge petition Monday if the speaker had not announced a floor schedule by close of business Friday. “We are done waiting for a process that does not exist,” Jeffries said at a hastily-arranged afternoon news conference in the Capitol’s Rayburn Room. By 4 p.m., 162 House Democrats had publicly committed to signing the petition, according to a tally maintained by the Democratic Whip’s office.

The White House response was muted and procedural. Press Secretary Karoline Leavitt, at the daily briefing, said President Donald Trump “has not yet been presented with the resolution” and declined to repeat the veto-question deflection she has used at each of the past three briefings. Two senior administration officials, speaking on condition of anonymity to describe internal deliberations, said the White House counsel’s office had finalized a signing-statement strategy under which the president would allow the resolution to become law without his signature if it cleared both chambers — a path designed to avoid a high-profile veto fight six months before the midterms while preserving the administration’s view that the measure does not bind future executive action.

“The president believes the resolution is unconstitutional,” one of the officials said. “He also believes that vetoing it during a recovery week, with Brent at $94 and pump prices falling, would be its own kind of mistake.”

The political backdrop hardened Friday morning when the Department of Labor reported preliminary April payroll growth of 196,000 jobs, near the upper end of the range Treasury officials had previewed earlier in the week, with unemployment ticking down to 4.1 percent. Treasury Secretary Mira Goldfarb, in a Rose Garden appearance with the president shortly before the Senate war powers vote, cited the figure as “the first clean print of the post-war economy.” Trump, who took no questions, said the country was “back in business” and called the day “a great day for America, despite what the Senate is going to try to do later.”

Reaction on the right was uneven. The Heritage Foundation called the seven GOP defectors “well-intentioned but mistaken,” while the libertarian Cato Institute praised the vote as “the first serious institutional pushback against executive war-making in a generation.” Two Republican strategists working on Senate races said the defectors had likely insulated themselves from suburban backlash without meaningfully alienating the party’s base, given the war’s successful conclusion.

“The vote everyone is going to remember is the one where the Senate said the next president has to ask,” said Karl Yoder, a Republican pollster who has been tracking war-related ballot tests in five swing states. “That polls in the sixties across the board. The supplemental is the harder vote, and the speaker knows it.”

Senate floor action on the supplemental resumes Monday at 3 p.m., with the first roster of amendments expected to focus on offsets, an independent reconstruction inspector general and the mental-health funding Collins has signaled she will add. House leadership is expected to meet over the weekend to set a path forward on both measures.

Aides to Johnson said a conference-wide meeting would be scheduled for Tuesday if no agreement on a floor schedule emerged by Monday morning.
