The U.S. Senate blocked a $1.15 trillion defense bill on July 14 in a 50-46 vote, with Democrats objecting to the Trump administration’s undeclared war on Iran and controversial provisions that would deepen military integration with Israel. The motion needed 60 votes to advance in the 100-member chamber, marking a rare setback for the National Defense Authorization Act, or NDAA, which has passed annually for more than six decades.
Senate Minority Leader Chuck Schumer urged Democrats to oppose the bill, calling it “a permission slip” for continued military operations against Iran without congressional oversight. “Trump started this war without authorization, without a strategy, and without an exit,” Schumer said before the vote.
But the Iran conflict was only one flashpoint. The defense bill also contained Section 224 (renumbered Section 219 in the House version), titled the United States-Israel Defense Technology Cooperation Initiative. According to Josh Paul, a former State Department director in the Bureau of Political-Military Affairs now at A New Policy, the provision creates a new architecture for U.S.-Israel defense collaboration premised on integrating the Israeli and American defense industries, especially in emerging areas of technology including artificial intelligence and quantum computing.
The provision would require the Pentagon to appoint an official to coordinate between the two countries on defense technology, including joint military research, weapons production, and the integration of each country’s technologies into the other’s military systems. It also controversially calls for “data fusion,” which Human Rights Watch defined as combining feeds from multiple sensors and intelligence sources into a single targeting picture.
Several Democratic senators, including Chris Van Hollen, Bernie Sanders, Elizabeth Warren, Ed Markey, Jeff Merkley and Peter Welch, urged colleagues in a letter not to advance the NDAA before the measures could be debated. “As Senate Democrats, we should not be providing votes compelling Trump to deepen the US relationship with Netanyahu’s extremist government,” they wrote.
Despite the Senate setback, the House passed its version of the NDAA on July 22 by a narrow 216-212 vote, keeping the Israel provision intact. The bill now faces a conference committee process where House and Senate negotiators must reach a compromise version before it returns to both chambers for final votes.
Paul warned that if enacted, Section 224 would pose direct challenges for U.S. national security. The provision opens sensitive areas of emerging U.S. technology to Israel’s national security establishment, which has a history of pursuing economic and defense-related espionage, he argued. Additionally, once Israeli technologies are integrated into U.S. military systems, Israel could threaten to withhold critical subcomponents or software updates, potentially holding U.S. military capabilities hostage.
Israel’s support in Congress has eroded significantly among Democrats. According to a June Reuters/Ipsos poll, Israel’s favorability rating among Democrats dropped from 59 percent in 2018 to 22 percent in May 2026. This shift reflects broader public opposition to continued military support for Israel, especially amid the ongoing Gaza conflict. The provision’s supporters argue it deepens strategic cooperation between the two countries, but critics contend it makes it nearly impossible for future administrations or congresses to unwind the relationship.
The NDAA is traditionally one of the few “must-pass” pieces of legislation in Congress, and the Senate’s blockade represents an unusual breach in bipartisan consensus. The bill will likely face intense negotiation in the coming weeks as Republican and Democratic negotiators attempt to reach a compromise that can pass both chambers.
