Garamendi's July 2026 amendments to the 2027 defense bill would force pre construction briefings and annual public impact reports on the military base buildout.
The Pentagon has been leasing land on U.S. military bases to private companies for AI data centers, and a group of lawmakers is now trying to slow that buildout through amendments to the 2027 National Defense Authorization Act. Rep. John Garamendi (D-CA) filed amendments in July 2026 that would require the Department of Defense to brief Congress on community impacts before construction starts and to publish annual public impact reports.
The program itself is already moving. The Army reached a conditional agreement with private industry for hyperscaled data centers earlier in 2026, with the lease footprint covering at least four installations. CoStar treats the lease-out as a real-estate play distinct from a traditional weapons program, and Mother Jones frames the buildout as part of the Trump administration's push to site data centers on public lands.
The core congressional objection, per Politico via Raw Story, is that data centers are "extraordinary consumers of both energy and water" — a line from Garamendi — and that Congress has not been briefed. "A bigger concern is that we haven't received the appropriate brief," Rep. Mike Levin (D-CA) told Politico.
What remains unknown as the FY2027 NDAA heads into markup: which private companies are being leased to, the lease terms at each site, and whether any Republican or committee-chair voices back the amendments.
