Defense Secretary Pete Hegseth on Monday unveiled the 15 members of a reconstituted Defense Policy Board, installing former U.S. Trade Representative Robert Lighthizer as chair and tapping venture capitalist Marc Andreessen for a seat on the advisory panel that had been cleared out more than a year ago.
The announcement caps a deliberate overhaul that began in April 2025, when Hegseth removed every sitting member of the board following an internal review. The Pentagon then formally reestablished the panel through a Federal Register notice in August 2025, and waited nearly a year before naming anyone to fill it.
The new roster signals that Hegseth wants advisers aligned with the administration's defense priorities rather than holdovers from previous eras. Lighthizer, who served as Trump's top trade negotiator during the first term, brings a hawkish economic-competition lens to a body traditionally populated by retired generals and Beltway defense hands. Former Sen. Norm Coleman of Minnesota will serve as vice chair.
Of the 15 appointees, only five have been publicly identified so far. Beyond Lighthizer and Coleman, the confirmed members include Andreessen, former Senate GOP candidate Blake Masters, and Michael Anton, who previously served as director of policy planning at the State Department.
The remaining ten names have not been disclosed. That gap leaves open questions about the board's overall composition and whether it will draw more heavily from the private sector, the policy world, or traditional national-security circles.
The Defense Policy Board, established in 1985, exists to advise the defense secretary, the deputy secretary, and the Pentagon's top policy official. Its portfolio covers regional defense policies, strategic planning, and the policy implications of force structure and modernization, weighty subjects at a time when the department is navigating simultaneous pressures in Europe, the Indo-Pacific, and the Middle East.
Andreessen's appointment will draw the most outside scrutiny. As a general partner at Andreessen Horowitz, he sits atop a venture portfolio with deep Pentagon exposure. The firm's investments include OpenAI, SpaceX, Skydio, Hadrian, and Anduril, all companies that hold contracts with the Department of Defense.
Whether those financial ties create any formal conflict-of-interest obligations for a board member remains unaddressed in the Pentagon's announcement. Advisory committees typically operate under federal ethics guidelines, but the specifics of how those rules will apply to Andreessen's situation have not been spelled out publicly.
That said, the administration has made no secret of its desire to bring Silicon Valley innovation into defense procurement. Placing a top tech investor on the board is consistent with that goal, and with the broader push to move the Pentagon away from legacy contractors and toward newer firms that can deliver capability faster.
Hegseth's decision to wipe the previous board clean was part of a far wider pattern of personnel moves at the Pentagon. He has systematically removed officials he viewed as misaligned with the administration's direction.
Earlier this year, Hegseth ousted the Biden-era Army chief of staff even as tens of thousands of troops were deploying to the Middle East. That move drew sharp reactions across the political spectrum, but the secretary pressed forward.
The shake-ups extended to the European theater as well. A top Army general in Europe stepped down after Hegseth moved to downgrade his command, a decision that fed ongoing debate about the U.S. force posture on the continent.
Not every Republican has cheered the pace of change. Some GOP lawmakers have publicly questioned whether the wholesale turnover has weakened institutional continuity at the department. Rep. Don Bacon, a retired Air Force brigadier general, broke with Hegseth and argued that mass firings had damaged the Pentagon's ability to function.
Hegseth has also faced pointed criticism from Sen. Thom Tillis, who took the secretary to task over the European troop drawdown and the forced removal of top generals.
In announcing the new board, Hegseth urged members to support the Pentagon's new strategic direction and policy priorities. But the announcement did not detail what those priorities are, or how the board's advisory role will differ from the one it played before the purge.
The original board had operated for four decades. Its members over the years included former secretaries of state, retired combatant commanders, and prominent academics. Clearing them out was a statement. Filling the seats with figures like Lighthizer and Andreessen is another one, a signal that economic competition, technological disruption, and alignment with administration goals will matter more than Beltway credentials.
The internal review that prompted the mass removal has never been made public. What it found, what it recommended, and whether it identified specific shortcomings in the old board's advice remain unanswered questions. Without that context, the public is left to evaluate the new panel on its roster alone.
The linked Department of War announcement, itself a notable institutional marker, given the URL references "war.gov" rather than the traditional Department of Defense branding, offers the formal record but little additional detail beyond what Hegseth disclosed Monday.
The board's first meetings, agenda, and public output will determine whether it functions as a genuine advisory body or a symbolic one. Advisory panels can shape policy in meaningful ways, or they can collect dust. The difference usually comes down to whether the secretary actually listens.
Hegseth has shown he is willing to make disruptive personnel decisions, even when they generate friction within his own party. The question now is whether the people he has chosen to advise him will push back when it matters, or simply validate directions already set.
At a time when reports have surfaced about internal White House deliberations over Hegseth's own standing, the secretary is building an advisory bench that reflects his instincts. If those instincts prove sound, the board will be remembered as a smart reset. If not, the names on the roster will share the accountability.
Washington has no shortage of advisory boards. What it lacks is advisers willing to tell a principal what he doesn't want to hear. That's the test this panel will face, and the one that actually matters.
