Key takeaway

A Republican AUMF, not a Democratic War Powers vote, is what could end the 59-day zero-instrument streak.

Senator Lisa Murkowski, Republican of Alaska, is targeting Tuesday 28 April to formally introduce an authorisation for use of military force (AUMF) on Iran, Jewish Insider reports⁠1. Susan Collins, Thom Tillis and John Curtis are on the record as backers. Murkowski has framed her draft as seeking "greater disclosure, greater transparency".

The fifth War Powers Resolution (WPR) failed 46-51 on Wednesday 22 April, the tightest margin of the war; Senator John Fetterman crossed to Republicans and Senator Rand Paul crossed to Democrats. The WPR operative legal deadline is Friday 1 May, sixty days from Trump's 2 March congressional notification of the 28 February strikes. If Murkowski's bill lands on 28 April, the first signed Iran congressional instrument of the war would arrive on a Tuesday, three days before the Friday deadline, and from the Republican side rather than the Democratic.

The 2002 Iraq AUMF granted authority that operated for 21 years; the 2001 terror AUMF justified operations in 14 countries the drafters did not envisage. If Murkowski's text reads as a licence rather than a leash, Trump would gain congressional cover for a war the White House has refused to sign for, which means a Republican AUMF could achieve what 59 days of Truth Social posts could not. The five energy Presidential Determinations and Enbridge pipeline permits signed across the same window confirm Trump's policy machine is working; it has simply not turned toward the war.

Deep Analysis

In plain English

The War Powers Resolution is a US law from 1973 that says any president who starts a military operation must get Congress to approve it within 60 days, or start withdrawing troops. That 60-day deadline falls on 1 May for the Iran war. So far, Congress has voted five times to end the war, and five times failed to pass that vote. Now Senator Lisa Murkowski, a Republican from Alaska, wants to try a different approach: instead of voting to stop the war, she wants to vote to formally authorise it. This is called an authorisation for use of military force, or AUMF. The key question is whether her bill would add real constraints on how the war is conducted, or whether it would give the president a legal rubber stamp for whatever he chooses to do. Every AUMF since 1973 has been interpreted more broadly than its plain text, per Brennan Center research.

Deep Analysis

Root Causes

Murkowski's AUMF has a structural origin in Republican Party dynamics: the WPR's five successive failures (all sponsored by Democrats and Rand Paul) established that the Senate will not pass an anti-war resolution. But three Republican senators (Murkowski, Collins, Tillis) have signalled discomfort with a 59-day war prosecuted on verbal authority alone. The AUMF is their mechanism for addressing the constitutional concern without opposing the war itself.

Murkowski's 28 April target date is set by the WPR deadline: without an AUMF before 1 May, Trump must either withdraw forces or openly defy the statute, both politically untenable. A pre-deadline AUMF eliminates the legal cliff, gives Murkowski a legislative win, and provides Trump with congressional cover he declined to seek. The AUMF resolves the constitutional problem without any party having to lose.

What could happen next?

Risk
If the AUMF passes with open-ended language equivalent to the 2001 or 2002 precedents, Trump gains retroactive congressional authority for 59 days of operations and forward authority for any escalation, removing the only remaining legal constraint on the war's scope.
Short term · 0.8
Opportunity
A narrowly scoped AUMF with reporting requirements and a defined geographic limit could establish the first formal congressional oversight mechanism of the war, creating a paper trail that subsequent administrations and courts could enforce.
Medium term · 0.55
Precedent
A Republican-sponsored AUMF becoming the first signed Iran legislative instrument of the war would demonstrate that the constitutional check on executive war-making runs through the majority party, not through opposition WPR votes, reshaping the precedent for future conflicts.

Primary parallel: The 2002 Iraq AUMF passed after 11 days of Senate debate and authorised force against Saddam Hussein's government and 'associated forces', language expansive enough to be cited for operations against groups that did not exist in 2002. It remained on the books for 21 years until formally repealed in March 2024. If Murkowski's Iran AUMF passes with equivalent language breadth, it creates a durable legal authority that could outlast any ceasefire by decades.

Counter-parallel: The 1964 Gulf of Tonkin Resolution, passed 88-2 in the Senate after a reported (later disputed) North Vietnamese attack on US destroyers, authorised the Vietnam War without a formal declaration. It was never repealed; Presidents Johnson and Nixon cited it for escalation until Congress passed the WPR in 1973 as a corrective. The pattern: blank-cheque military authorisations passed under time pressure have never been narrower in practice than they were on the day of passage.

Consensus view: Georgetown Law's Rosa Brooks and the Brennan Center for Justice's Elizabeth Goitein both assess the AUMF as a vehicle that could formally vest congressional authorisation retroactively: because the WPR's 60-day clock runs from Trump's 2 March congressional notification, a bill introduced on 28 April and passed before 1 May would cure the constitutional deficiency even if it authorises an operation already 59 days old.

Brooks notes this was the precise mechanism used by Congress in 1942 to ratify Roosevelt's internment executive order, though that precedent is now understood as a failure of legislative oversight rather than a constitutional model.

Counter-view: Cato Institute's Gene Healy and Quincy Institute's Ben Freeman argue Murkowski's framing of 'greater disclosure, greater transparency' signals a leash-type AUMF rather than a licence: bills drafted with reporting and disclosure requirements have historically been amended on the floor to remove constraints and become broader authority grants.

The 2001 AUMF, originally confined to 9/11 perpetrators, justified operations in 14 countries through executive interpretation alone. A Republican AUMF passed by a Senate that just rejected the WPR 51-46 is more likely to expand Trump's authority than constrain it.

Key tension: Whether Murkowski's text, when filed, will contain enforceable reporting requirements and a geographic or temporal scope limitation, or whether it will be amended in committee or on the floor to become the unconstrained authorisation the WPR was supposed to prevent.

Different Perspectives

French Football Federation

The FFF called an 11:00 CEST press conference for 28 July, at its Paris headquarters, following an extraordinary executive committee meeting, at which Zinedine Zidane is expected to be presented as head coach succeeding Didier Deschamps. As of this writing no communique confirms the appointment, contract length or start date.

Morocco

Morocco is pushing for the 2030 final at its Grand Stade Hassan II in Casablanca, a planned 115,000-seat venue that would be the world's largest football stadium on completion. The venue is contested by a Spanish petition for the Santiago Bernabeu, and FIFA has fixed neither the venue nor the tournament's proposed 64-team format.

FIFA

FIFA's first tournament report, published 27 July, itemises nearly 300,000 accredited personnel, 73,700 security staff and 300,000 square metres of custom-grown turf, with no revenue or cost figure attached. As a Swiss association answering to its own Congress rather than a treasury, FIFA has followed the same operational-before-financial sequence it used after Qatar 2022.

Javier Tebas / La Liga

La Liga president Javier Tebas said on 21 July that FIFA's system is rotten from the root and that Gianni Infantino's time as president has, in his words, concluded. Tebas has no vote in FIFA's process, so days after the IOC declined jurisdiction over a separate ethics complaint, he used the only instrument he has.

Mexico City government

Head of government Clara Brugada presented a closing report on 22 July crediting the tournament with 44 billion pesos of economic activity, 2,000-plus accelerated public works and 100,000 formal jobs in June alone. The city has not published the method behind that figure, and three other Mexican bodies count the same five weeks differently.

Town of Foxborough

Foxborough answered Kraft Group's June lawsuit on 7 July with a 61-page counterclaim, calling the stadium's owners 'a collection of multibillion-dollar corporations' trying to shift its $7.8 million security bill onto taxpayers. The town says its licensing power and its billing power run through the same board, and it wants the court to award its own costs too.
