Summary
The Department of War announced the appointment of a newly constituted Defense Policy Board with Marc Andreessen among 15 newly approved members selected by Secretary Pete Hegseth. The Defense Policy Board serves as a centuries-established advisory committee tasked with providing independent and strategic counsel to senior Department of Defense leadership on matters of national security and defense policy.
Former U.S. Trade Representative Robert Lighthizer, who served during the first Trump administration from 2017 to 2021, will chair the reconstituted board, with former Minnesota Republican Senator Norm Coleman serving as vice chairman. Beyond Andreessen, the 15 appointees include retired Navy Admiral Chas Richard, who commanded U.S. Strategic Command; Blake Masters, a former Arizona Senate candidate; and national security specialists including Michael Anton, Rachel Bovard, Tom Feddo, Mike Garcia, Kenneth Jones, Michael Pillsbury, Francis Sempa, Christopher Williams, and Theo Wold. According to the Federal Register notice published in August 2025, the board is composed of members with distinguished backgrounds in defense and national security affairs, with membership capped at 20 individuals.
Secretary Hegseth initially dissolved the previous Defense Policy Board in April 2024 following a 45-day review. The appointment of Andreessen, owner of venture capital firm Andreessen Horowitz, underscores the administration's integration of Silicon Valley leadership into defense policy formation. Andreessen's firm has been instrumental in championing defense tech reform and has seeded numerous companies targeting defense modernization since 2016. Board members serve between one and four years with annual renewal options and are appointed to provide advice based on independent judgment, free from conflicts of interest, though Federal Register guidance emphasizes they must operate without representing particular viewpoints.
The appointments reflect continuity with patterns established during the previous Trump administration, when numerous defense and security officials were replaced with administration-aligned figures. Andreessen's presence on the board aligns with his firm's growing focus on defense industrial policy and his documented political support for the current administration, having donated $3 million to MAGA Inc., a Trump-supporting super PAC, during the first half of 2025.
