The House of Representatives on Wednesday night approved its version of the fiscal 2026 National Defense Authorization Act, passing the annual defense policy bill 231–196 after a prolonged series of roll-call votes that exposed deep partisan divisions.
For decades the NDAA had been a bipartisan measure, but this year’s package fractured along party lines as Democrats protested a slate of Republican-led amendments addressing transgender service members, the display of flags on military installations and vehicle procurement preferences. Seventeen Democrats joined most House Republicans in supporting final passage, while 192 Democrats voted against it.
Lawmakers debated and voted on numerous amendments that Democrats said injected culture-war issues into a must-pass national security bill. Rep. Nancy Mace, R-S.C., secured several measures that Democrats say target transgender service members, including restrictions on spaces that transgender service academy cadets may access. An amendment from Rep. Jimmy Patronis, R-Fla., aimed to remove procurement preferences for electric and hybrid motor vehicles within the Department of Defense. Rep. Cory Mills, R-Fla., won an amendment intended to prohibit pride flags or other ideological banners on military installations.
Top House Democrats, including Minority Leader Hakeem Jeffries of New York and Rep. Adam Smith of Washington, the ranking Democrat on the House Armed Services Committee, opposed the bill’s final passage after GOP amendments were included. Smith had warned he would vote against final passage if the contested provisions were adopted, saying the changes “focus on divisive topics rather than strengthening our national security.” He said the rule for floor consideration undermined a long-standing tradition of bipartisan cooperation on the NDAA and criticized the House Rules Committee for filtering out Democrat-led amendments prior to the floor debate.
Democrats who rose on the floor criticized several amendments as punitive or unrelated to readiness. Rep. Sara Jacobs, D-Calif., defended gender-affirming medical care in a floor exchange that drew an angry retort from Mace, who called Jacobs’s remarks “ridiculous.”
Four Republicans joined Democrats in opposing final passage. Rep. Marjorie Taylor Greene, R-Ga., and Rep. Thomas Massie, R-Ky., were among those who voted no, reflecting ongoing GOP fractures over elements such as foreign aid and the overall direction of defense spending. Democrats who crossed party lines to support the measure included Reps. Jared Golden of Maine, Marie Gluesenkamp Perez of Washington, Don Davis of North Carolina, Henry Cuellar of Texas and Vicente Gonzalez of Texas.
The NDAA sets defense and national security policy, authorizes military programs and establishes spending priorities, although it does not itself appropriate funds. After passage in the House, the Senate is expected to consider its own version of the bill. Lawmakers in both chambers must reconcile differences in a conference before producing a final measure to send to the president for signature.
The partisan rift in the House follows a recent pattern of shrinking bipartisan support for the NDAA, a trend that lawmakers and analysts say can complicate delivery of long-standing military and national security priorities. Republicans framed several amendments as efforts to uphold standards and priorities within the military, while Democrats argued the measures politicize personnel and readiness issues and could undermine recruitment and retention.
Floor managers moved quickly through the final votes after hours of debate, and staff began laying the groundwork for the next legislative steps. The Senate Armed Services Committee typically crafts its text in parallel; a House–Senate conference would be expected to resolve disparate positions on the contested provisions, including the transgender-related limits and procurement language.
With the House bill now approved, attention will turn to the Senate calendar and to negotiations between the two chambers. Passage of a reconciled NDAA remains a central legislative objective for both parties, but this year’s partisan division in the House illustrates how broader political disputes have become entwined with the congressional defense-authorizing process.
