Rule Changes

Pushed for higher defense topline, stronger Ukraine backing, and new constraints on Trump’s war powers

In December 2025, Congress completed work on the Fiscal Year 2026 National Defense Authorization Act (NDAA), authorizing a record $901 billion in national security spending. The House passed the final compromise 312–112 on December 10, and President Donald Trump signed the bill into law on December 18 in a low-profile move without an Oval Office ceremony. The enacted package cements a 4% pay raise for service members, provides $800 million for Ukraine over two years through the Ukraine Security Assistance Initiative (USAI), advances Trump priorities such as eliminating Pentagon DEI programs and supporting the “Golden Dome” missile-defense effort, and retains policy riders that helped drive intra-party and bipartisan friction.
