Sen. Chris Van Hollen, D-Md., and 10 other senators are urging congressional leaders to remove three provisions expanding U.S. military and intelligence cooperation with Israel from the fiscal year 2027 National Defense Authorization Act (NDAA).

In a letter sent Tuesday, the lawmakers argued that the measures could restrict President Donald Trump's authority over national security decisions while creating long-term commitments that increase American dependence on Israeli military technology.

Two of the provisions would establish a United States-Israel Defense Technology Cooperation Initiative, expanding joint work on weapons development, artificial intelligence, biotechnology, quantum technology, autonomous systems and cyberwarfare. The senators warned that joint production agreements could give Israel influence over the availability and distribution of American military equipment.

They cited a previous dispute involving Iron Dome missile defense systems, claiming Israel used its production agreement to prevent American batteries from being sent to Ukraine.

The third provision would require the executive branch to expand intelligence-sharing with Israel while prohibiting the suspension or significant reduction of that cooperation. The senators argued that the requirement could prevent Trump from limiting intelligence exchanges when doing so might be necessary to protect U.S. interests.

The letter also criticized Israeli Prime Minister Benjamin Netanyahu's push to shift the defense relationship away from traditional military aid and toward joint weapons development. The lawmakers said moving more assistance into defense acquisition programs could reduce transparency compared with conventional military aid arrangements.

Van Hollen was joined by Sen. Bernie Sanders, I-Vt., and Democratic Sens. Elizabeth Warren and Ed Markey of Massachusetts, Peter Welch of Vermont, Jeff Merkley and Ron Wyden of Oregon, Brian Schatz of Hawaii, Patty Murray of Washington, Tina Smith of Minnesota and Andy Kim of New Jersey.

The senators are asking House and Senate leadership to remove the provisions as lawmakers negotiate the final version of the annual defense authorization legislation.
