Republican lawmakers have lost crucial opportunities to limit President Trump's military authority in Iran after months of deference. The GOP-controlled Congress missed both the 30-day window for introducing war authorization bills and the 60-day deadline under the 1973 War Powers Resolution that fell on May 1. This inaction effectively ceded control of the Middle East conflict to the executive branch.

Senator Lisa Murkowski drafted an authorization requiring clear exit criteria but never introduced it, lacking sufficient Republican support. The administration now claims the war ended with a cease-fire, arguing the 60-day clock stopped. Legal scholars dispute this interpretation, noting the War Powers Resolution doesn't recognize cease-fires as pausing hostilities clocks.

Representative Don Bacon joined other Republicans opposing unilateral war powers, calling Trump's approach like a teenager violating curfew. Three more Republicans defected this week, joining Democrats on war powers votes. However, authorization measures face long odds without the required 30-day introduction window.

The political fallout arrives during a challenging midterm election year where Republicans risk owning an unpopular war. Senator Murkowski warned that every aspect of the conflict will be directly attributable to the president and Republican majority who enabled it through congressional inaction.
